[NEW SCRIPT PROPOSAL] Script to increase performance for AMD THREADTHRIPPER

[mrdev023]

Moved issue from https://github.com/starcitizen-lug/lug-helper/issues/42

I write a script to increase performance with my Threadthripper 2990WX. But i don't know how to integrated it because this script need to be run before and after playing at Star citizen.

After

This script can work if each core is split to multiple PU.

lstopo # Show CPU topology 

Example of display:

Core L#0 is split in 2 Processing Unit, so if i disable the second PU for each Core. Star citizen performance is improved.

configure_sc.sh enable # To enable disable useless core

configure_sc.sh disable # To enable all cores

@beniwtv this might be useful info to add to our wiki under performance tuning? Lutris can use the pre/post script settings to automatically run these configurations

[beniwtv]

Yep, though I am unsure if this can be launched by Lutris, as it requires superuser privileges. But at least we can upload it here and link to it.

Can't you use WINE_CPU_TOPOLOGY for this use case?

[mrdev023]

I try with WINE_CPU_TOPOLOGY configuration

[mrdev023]

I had try this WINE_CPU_TOPOLOGY=32:0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62 but it doesn't work

[Megalomaniak]

Something like this should work for first gen AM4 cpu's too? They feature multiple CCX's too so I'd think so...

[gort818]

You can try it like this WINE_CPU_TOPOLOGY=16:0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 or WINE_CPU_TOPOLOGY="25:0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24note you will probably need a protonified wine build like glorious eggroll or tkg

[mrdev023]

It work better with WINE_CPU_TOPOLOGY=16:0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 average 54 fps in same position

Doesn't look like this has been added into the wiki yet. If someone can help me out by writing up a list of instructions and which CPUs might benefit from this, I'll add it to our performance tuning section. If the environment variable can do the same thing as the script, I think we'd prefer that solution.

See https://github.com/starcitizen-lug/information-howtos/wiki/Performance-Tuning for formatting

@mrdev023 Pull requests can now be submitted against the wiki. If you'd like to help write this up in our performance tuning section, please go ahead and create a PR. Thanks! https://github.com/starcitizen-lug/knowledge-base/tree/main/wiki

I started a write up for this, it needs some edits, as stated in the commit message. I cant verify these steps since my ryzen cpu only has one die. Will continue editing it "tomorrow"

[RampedIndent]

Just a thought, but this might also help on Intel cpus with performance and efficiency cores.
