Any recommended benchmarking utilities?

–mini mode of mini-benchmarker:
https://aur.archlinux.org/packages/mini-benchmarker

to visulize the results:

Lets start.
Here you can find scx_rusty against EEVDF-BORE on the 6.9 Kernel.
scx_rusty was build from commit Merge pull request #261 from sched-ext/rusty_interactive · sched-ext/scx@efb97de · GitHub

tldr:
Rusty does really compete with EEVDF-BORE. The perf sched regression is the only “bigger” one, but all in all it is looking really good.
dvernet is working to fix the perf sched regression.

Rusty is also since the above commits very responsive under heavy load and rusty gets slowly to the path for a very good scheduler.

I made a little comparison of rusty, lavd and bore in Rocket League and spotted two differences.

AMD Ryzen 5700X + Nvidia RTX 3060Ti + 16GB RAM 3200MHz
6.9.0-rc6-3-cachyos-rc + scx-scheds-git 0.1.9.r40.g07b521b-1
amd_pstate=active mitigations=off
X11 + KDE
PBO and c-states disabled
performance governor

  1. FPS stability.

BORE can maintain 359.XX FPS (with cap to 360 FPS in game.) but lavd and rusty constantly droping to 355 on rusty and even 340 on lavd.

  1. Latency.

Game Thread latency on BORE is around 0.60, on rusty around 0.80 and lavd around 0.90.

Moreover Game Thread MAX latency is spiking in moment when screenshot is taken so this value is not credible on screenshots.

Link to explanation what this statistics exactly mean.

Long story short - no significant differences. With each configuration I did two runs but I add only one screenshot with better result. Additionally I tested SMT ON/OFF/Auto Reflex ON/OFF and VSync ON/OFF but there was no differences in scores. Number after scheduler name is benchmark run order. Originally I planned add all screenshots.







The important question is how cpu limited are you?

Game:
Cyberpunk 2077 v2.12
Game settings:
Graphic settings lowest possible with DLSS Ultra Performance
Hardware:
AMD Ryzen 7 5700X + Nvidia RTX 3060Ti + 16GB RAM 3200MHz

linux-cachyos-rc 6.9.rc6-4 + scx-scheds-git 0.1.9.r40.g07b521b-1
linux-cachyos-rc-lto 6.9.rc6-4
linux-cachyos-echo 6.8.9-1

Governor:

This time I tried to reduce GPU bottleneck. Now we have some differences so I add all screenshots. I did all benchmarks at one fell swoop so I run one more BORE extra to see how performance can be degraded when CPU is heated. Exactly order is BORE 1&2 next Rusty 1&2 next Lavd 1&2 then BORE 3. The remaining tests required restarts so heat was lower.














New kernel linux-cachyos-rc 6.9.rc7-1 and mitigations ON / OFF




i think a lot of space could be saved if perhaps we just posted the fps results in text lol

Hi, I’m new to cachyos.

I tried cachyos-rc kernel, the results are more details on graphics, less stutter, better brightness but less fps (1-2 fps) than cachyos non rc kenel.

None of that sounds right. Im sorry to say this but if youre as new as you sound. Best you dont post here. go ask the discord for help

Anyway. Looks like having SMT off on cyberpunk for my 5800x very much improves fps

I have no problem on fps. everything else is great even better than any other distros. Cachy Os is the best right now
