7950X3D and process lasso

[Mando772004]

i downloaded process lasso and set everything to run on the frequency cores and i will set the games to run on the cache cores, i heard this reduces latency and reduces micro stutters, mind you i do have prefer cache on. is there anything i should be careful of when using process lasso? anything to avoid or any tips in general? I am using windows 11 pro if that helps in anyway and everything is updated including game bar and xbox app and windows itself of course

Calling @Agall, i'm sure they will have some input here.

I'd say ignore all of that.

 

Have the 3D v-cache optimizer driver installed as AMD suggested, but there's a UEFI setting that entirely negates the issues you're describing. It effectively forces CCD0 and disables that driver.

 

If you go to CPU Advanced settings, SMU, then CPPC Preferred Cores and set it to 'cache', it'll always prioritize CCD0. It'll 'park' CCD1 with this but I see it get a bit of use for background tasks occasionally.

 

I've played with these settings and the driver is the default 'auto' setting here. I experienced the same microstuttering you're describing likely because its negotiating across the CCDs when it shouldnt. 

 

The only downside to this setting is that heavy single threaded tasks like a Cinebench R23 run won't use CCD1 but CCD0. It effectively turns it into a 7800x3D with 8c/16t CCD1 on standby which I think is how most people want to use it.

 

 

Note that the full 16c/32t single threaded run has the performance of the 3D v-cache only run. That's because its using CCD0 and not CCD1, something the driver would allow. Something you could technically work around with Processor Affinity settings in Task Manager for a specific app that for some reason wants the extra 700MHz of CCD1.

 

I've tried for months to get Youtubers to test and demonstrate this, but none of them seem to notice my comments. The scenarios where the 7950x3D doesn't beat or at least match the 7800x3D are entirely due to the driver's poor optimization, something this setting completely negates.

this microstutters are a bit annoying which is why i wanted a fix, i already have prefer cache on but i think sometimes the games switch to the 2nd ccd which causes that small stutter then goes back. is there no fix?

You can test that by changing Processor Affinity settings in the Detail section of Task Manager for the specific application. Disable Cores 16-31 (starts at 0) for that application and see if you still get them. That'll force that application onto CCD0 and see if the microstutters are from the 7950x3D hardware configuration or not.

 

You could also disable CCD1 in the UEFI by reconfiguring the CCDs to see if that solves the issue as well. That'll point towards your theory about spillover into CCD1.

i tried and it still had small microstutters, theyre rare and theyre not  gamebreaking but im guessing it could be cuz the game is running at like 400+ frames, game im talking about is Rainbow Six Siege

Are you using the Balanced Power Plan or did you set it to High Performance?

 

You might otherwise need to do a fresh install. If any, uninstall the Chipset driver and full reinstall it. The chipset driver alone can cause these sorts of issues if its not proper.

im using balanced power plan. i think its just a game issue, i did go to my friends house and played many games and also noticed some microstutters in many games and he is on intel, it could just be normal, i mean they are very small and rare, cuz also i did like 20 reinstalls, like clean reinstalls for windows and no matter what i still sometimes get them, even on my older pc with a 3080 i used to get them

https://www.youtube.com/watch?v=0LagZPIWtMs you can see in this video that when he plays on 2k low which is somewhat similar to my settings, he also gets these occasional micro stutters, im guessing its just a game issue like i said

I've played a ton of R6S on my 4090 and 7950x3D as well, try different APIs between directx and vulkan. I think I normally ran vulkan.

 

I dont have the game updated, but there's probably some settings you can change to prevent this issue entirely.

im running dx11, i dont know tbh maybe its a dx11 issue
