Z2E Performance find

I have an interesting find in regards to Z2E performance.

I installed Steam OS on my Legion Go 2 last night. Got tired of coming home to see that windows woke up and the OLED screen had been on for god knows how long.

I loaded up KCD2 and noticed the typical 5-10% uplift from steam os. All of my testing is at 35watt TDP. Where I was standing on my save went from 54fps on Windows to 60fps on Steam OS with medium settings with fsr quality.

Not being satisfied I installed a decky curve optimizer plugin. Pretty sure it worked since it crashed the Steam UI at -15. I set it at -12. Maybe 1 or 2 fps improvement.

Optiscaler crashed in windows on KCD2 with frame gen, so I tried that out on steam os. It was alright. Base frame rate dropped to 40s and output 70-80fps. Didnt feel worth turning on.

I set a fixed gpu clock at 2400mhz and gained a legit 10fps while standing inside my forge.
Without this setting gpu clocks were 1.6-2ghz. 2400mhz is the sweet spot, higher than that tanks fps, lower drops it slightly.
CPU clocks dropped from the 4ghz range to 2.8-3.5 ghz.

Now I am running native res, fsr balanced, high settings with frame gen at 60s-80s fps in Kuttenberg.

I assume the TDP load balancing algorithms are crap on the Z2E and are holding it back. I have tried fixed clocks on the steam deck and ally x to no real effect.

I am tempted to use smokeless and raise the tdp cap to see if anything else is left on the table. Maybe I could get another 100-200mhz on the gpu or some more cpu speed.

Update: With further testing the 10fps boost I saw was not across the board. It is only that large with frame gen turned on and higher settings.
Benefit is highest when the shader cores are being hammered. Lower details yield nothing to a few fps increase. While higher settings have a more tangible result.

IIRC the main difference between Z1E and Z2E is shader count. Perhaps the ROPS and TMUS are choked by bandwidth or power and the shader cores are able to do more work by forcing the clocks higher. Which would allow for a higher budget on more shader heavy settings.
While not boosting performance on the low end. It may allow you to move from low to medium settings or medium to high at a simliar fps target.
 
Is there a curve optimiser for Z2E on windows? Ryzen Master maybe?
 
The Universal x86 Tuning Utility does everything. Actually, this is way better than anything else I've used to tweak settings, it even has all the settings available in the Radeon Software (which windows keeps uninstalling), and it's own scaling, impressive!

I tried it for TDP before installing steam os, then I remembered you have to use smokeless first.

Is smokeless to unlock a higher TDP? I'm not really interested in doing that since Z2E sweet spot is 30W, scaling is much worse after that.

Also, I repasted my MSI Claw yesterday and boy the cooling solution is pretty mediocre, the heatsinks on the heatpipe are ever so tiny. No wonder it gets so toasty.
 
Yeah it’s basically a supplemental bios you can boot off a flash drive to change settings. Be careful though. You can brick it if you change the wrong thing.
 
I found Handheld Companion about a week ago.

It does everything; complete replacement for factory software, handles RGB (without using dodgy ring0) controllers, with the ability to change polling and input type (xinput, directinput) which works flawlessly with certain games that support gyro (recent Zelda titles work real nice), TDP and fan adjustments, complete with per-game profiles, sleep optimisations, a nice overlay.

The only thing I don't like is that I can no longer hold the x-box button to bring up task view, but Handheld Companion sees all controller buttons so I just use the claw button instead, and use button combos for shortcuts which is great.
