[Six of Crows spoilers in this paragraph] Hey did I mention that the scene where Kaz tore out that dude’s eye after Inej got hurt made me go absolutely feral?  Because pinterest knows me about as well as I know myself (in contrast to tiktok which knows me better than I know myself and instagram which barely knows me at all) the app showed me a SoC textpost (still haven’t finished Crooked Kingdom lol) and it took me down a rabbit hole (apparently there’s going to be a show???? [edit: apparently Shadow and Bone is the show???  I haven’t even watched that, but I know it’s supposed to be good]) which reminded me of that scene in particular.  For someone who considers herself to be awfully soft-hearted, apparently my love language is gore.  Or, rather, an intelligent man who will tear the world to shreds if it lays a finger on me.  (Now look.  There is something that could be said about potential toxicity in the Kaz/Inej dynamic especially because he bought her but I’m a simple girl and simply have chosen to overlook this.)  

ALSO APPARENTLY THERE’S GOING TO BE A NEW PERCY BOOK FROM PERCY’S POINT OF VIEW WITH THE ORIGINAL TRIO???  Step aside Swifties, the old school pjo fans are quaking this year.

Speaking of media, the Halo show is getting a season 2!!!  I’m really excited for it actually.

And you know what?  As annoying and nerve-wrecking as it is, I actually am thankful that I’ve been forced to send out so many emails this semester.  Emails have become a lot less terrifying and more of just a thing to do to contact someone, and I welcome that shift.  In the year before (hopefully) going out into the real world (more or less (like I won’t receive the same coddling as undergrad but I will still be in school so)), I’m getting the practice which is great, truly.

THAT SAID.  I did get an email from a potential collaborator tonight as in nine pm on a saturday which was basically “im not taking students but yea id coadvise ig” and I have this awful habit of taking indifference/apathy toward me as dislike, and I am purposefully not allowing myself to go down that road today (also what is this lady doing on her work email on a saturday do you want me to think you have no life like,,, i at least fake it by schedule-sending all of my emails).  Look, ultimately, it’ll make my application stronger even if I haven’t had the opportunity to actually speak with this woman about what it might look like.  It’s fine I’ll be fine.  Everyone is certain that I’ll have A Decision to make, and I think I’m nearly at the point of believing them which is... I mean it’s a nice change of pace!  We’ll see how I feel closer to my deadlines and after them!

Second, I am thankful that I have a good relationship with my sister.  We went to see a wind ensemble performance last night and a football game today and while I was far more interested in the performance than the game (my sister was really into the game but my heart rate did not once increase, uhm, I could’ve cared less, but not by much (I did bring a book to read with me in case I got too bored, but it never reached that point and also that would’ve made me look like a main character in a Wattpad self-insert fanfiction so I couldn’t bring myself to do it and also my little band kid heart liked watching the marching band go brrr)), they were both still fun.

[edit: it’s ten now and my pop gen professor has also just replied to an email of mine, can... can tenured folk chill out?  I pray for their rest, truly (though I suppose it makes sense to be on top of your inbox because you’re a well-known professor and it could be easy for actual important communications to slip to the bottom)]

New Switch mod delivers real-time CPU, GPU and thermal monitoring

Back in the day it was all about FRAPS. These days, Riva Tuner Statistics Server and OCAT are the tools of choice. For decades now, PC users have relied on real-time on-screen displays with frame-rate counters and system monitoring tools to give them some idea of how their PCs are being utilised during gaming. But what if similar tools were available to console users? Remarkably, a recent breakthrough in Switch modding has made this a reality. Frame-rates, CPU/GPU utilisation, temperature monitors, fan speeds: all are exposed, giving us a fascinating insight into how Switch titles pushe the hardware during gaming.

Of course, this is all limited to earlier Switch revisions, vulnerable to a recovery mode hardware exploit on which custom firmware was developed. Yes, you can run these tools yourself but there is a route to piracy here – so not surprisingly, consoles attached to Nintendo’s online gaming service are routinely banned. But the interesting part from the Digital Foundry perspective is the flourishing homebrew environment, which recently saw the release of the Tesla frame-work – code that runs on the Switch’s reserved CPU core, bringing up an interactive overlay at any time during gaming. Tesla was swifty followed by the release of the Switch overlay mod, which essentially builds much of Riva Tuner Statistics Server’s functionality onto the Tesla foundation. Voila: full real-time system analysis – but what does it reveal?

Well, at the most basic level, you get instant confirmation that Nintendo does indeed reserve one of the Switch’s CPU cores for the OS and front-end – the overlay shows cores zero to two essentially dormant while navigating the shell, with only core three active as the menus are traversed. Similarly, there’s on-screen confirmation that Switch’s docked clocks are totally locked during gameplay: 1020MHz for the CPU, 768MHz for the GPU, 1600MHz on the EMC (embedded memory controller).

However, there is a twist and it’s something we’ve covered before, that we can now see play out in real-time – Nintendo’s ‘boost mode’. This amounts to optimisations in how certain games selectively overclock the CPU to improve loading times. For example, when you die in Mario Odyssey, the screen fades to black and the game loads you back to the last checkpoint. There is a fairly quick turnaround in Odyssey but this is faster thanks to boost mode. During loading, the CPU gets upclocked temporarily to 1785MHz – a 75 per cent increase on the stock clock. Meanwhile, the GPU actually drops all the way down to 76.8MHz – a tenth of its usual speed. Nintendo is balancing thermals by overclocking one component to the max, while downclocking another to the bare minimum.

Riva Tuner Statistics Server for Switch? The System Overlay mod delivers a ton of RTSS functionality on a console for the first time and the results are fascinating.

This technique is used in plenty of modern titles: Wolfenstein Youngblood, and even Crash Team Racing take advantage, while Zelda: Breath of the Wild and Super Mario Odyssey were patched to include it. Loading times are predicated not just on the speed of the internal NAND storage or your SD card, but also on the CPU decompressing assets in the background. With the screen being blank or static, there’s no need to have the graphics processing running at full power anyway. At least, not for this moment. At the first sign of gameplay, the Switch reverts back to default clocks. Boost mode certainly does the trick – I noticed around seven seconds lopped off the loading time from the main menu to the Great Plateau in Breath of the Wild – 23 seconds vs 30 seconds.

The system monitor overlay also reveals how certain titles have pushed Switch hardware to the point where Nintendo has stepped in to provide tweaked performance mode at the OS level – something that, outside of boost mode, only applies to portable configurations. When we first revealed Switch’s clocks, CPU was locked to 1020MHz, GPU to 307.2MHz. Just prior to launch, portable graphics were boosted to a more reasonable 384MHz. These days, Switch’s most challenging titles run the GPU at 460MHz – but that’s just part of the story.

Mortal Kombat 11 is a classic example. After the arena’s loaded in, the GPU boosts to 460MHz from the opening cutscenes to gameplay. It’s an exceptionally high clock speed, but it’s limited to gameplay only. Back at the menus we go back to 384MHz again. Super Mario Odyssey uses the same improved GPU clock, but there are some surprising releases that don’t. Hellblade: Senua’s sacrifice would likely benefit from the higher frequencies – its dynamic resolution would be higher and its frame-rate more solid, yet it’s running locked at the standard 384MHz.

How fast and how capable is a Nintendo Switch running key games at its very fastest CPU and GPU clocks? Find out right here.

It’s the same situation with Link’s Awakening, which struggles with its frame-rate, in certain scenes and which in the past has shown significant improvement via overclocking. Perhaps the developers opted for standard clocks in order to preserve battery life, as users are more likely to put in extended game sessions on an RPG. There is an interesting postscript to Link’s Awakening analysis. Yes, overclocking the GPU helps to iron out its frame-rate problems but the CPU and GPU monitoring suggest that there’s still plenty of performance left in the silicon when these stutters kick in, suggesting that the problem is elsewhere.

One of the most fascinating results from the system monitor tool is the concept of dynamic changes to clocks in portable mode. Games that use it are few and far between, but Luigi’s Mansion 3 has the ability to swap dynamically between 307.2MHz and 384MHz. It’s as is the Switch is able to throttle back its GPU in less demanding scenarios in order to maintain as much battery life as it can. Meanwhile, in the id Tech 6 ports from Panic Button, GPU clocks run the gamut, switching between 307.2MHz, 384Mhz and 460MHz. A while back, patches were released for the earlier id Tech 6 ports that improved performance and I wonder if it’s related to this.

The system monitor overlay also gives us detailed information on Switch’s thermals too. While docked, Doom and Wolfenstein are generally the titles that get the fan speeds revving highest. – and that makes sense when you see the temperatures. In an air conditioned office at 22 degrees Celsius, these two take no time at all to push the PCB heat sensor to 60c and to 55c on the Tegra X1 SoC itself. All of this gets the fans moving at 47 per cent speed max. Higher is obviously possible but with consistent test conditions it’s always these two titles that get the warmest results – along with Luigi’s Mansion 3 bizarrely, which hits the same peaks in temps and fan speed. Given these are all technical powerhouse games, all of which hammer the CPU cores to the high 90 per cent region, it does make sense. Equally, it highlights potential headroom we have for overclocking, assuming we’re avoiding boiling point 100c temps here – 60c is still a safe point. The biggest issue we’ve encountered with overclocking is simply down to acoustics. Push CPU and GPU too far and the fan noise becomes seriously intrusive.

Switch modding is branching out to games too. Many of the mods made to The Witcher 3 actually made their way across to the latest official patch for the game.

but perhaps increasing clocks still further to a certain extent is on the Nintendo roadmap. If so, our tests continue to demonstrate that the best bang for the buck boost to the Tegra X1 is – perhaps surprisingly – to overclock the CPU. Our understanding is that Nintendo has a developer mode which puts the CPU at 1220MHz – a 19.6 per cent improvement to standard clocks. Our tests demonstrate that doing so via homebrew OC tool sysclk doesn’t melt the battery and helps to mitigate a lot of performance problems in many, many games.

The system monitor overlay shows that titles like Smash Bros Ultimate, Doom, Wolfenstein and Luigi’s Mansion 3 all push the CPU to over 90 per cent utilisation – and extra overhead there could certainly help to boost performance. A quick test in Wolfenstein Youngblood shows a big improvement in overall fluidity, for example, right from the very first level. Nintendo has proven willing to adjust performance profiles on Switch as we’ve seen with the dynamic GPU speeds, boost mode for improved loading times and the 460MHz portable configuration. it stands to reason that there could be more down the line, hopefully for the CPU side this time.

Whether it’s through access to the silicon for monitoring purposes, overclocking system components or even tweaking games (as we saw recently with The Witcher 3), the work being carried out on the system by the modding community has allowed us to get a much deeper, fuller understanding of how the console hybrid works and how Nintendo continues to evolve its performance. The system monitor overlay in particular shines a light on how versatile the machine can be and where the hardware can be pushed via a delicate balancing act between thermals, fan speed, GPU load and performance. It’s the most comprehensive look at how a current generation console performs – and it’ll be fascinating to see where Nintendo takes it next.
