I know for a fact the scheduler will spread threads across both CCDs on my CPU, it's sufficient to simply pause one of the CPU folding slots and open the task manager's CPU load graph section (set to logical processors) to see this in action. Who knows how much performance is lost by Winows' braindead scheduler spreading a folding slot between two separate CCDs (maybe more than two, in case of a Threadripper/Epyc processor.)
How to use process lasso for ryzen free#
I tried using Process Lasso to limit one of the CPU folding slots to logical cores 1-15 only, and the other folding slot to logical cores 17-32 (leaving one logical core free per CCD), but it seems Process Lasso is unable to distinguish between multiple instances of the same executable, and would set both folding slots to utilize the same set of CPU cores (rrrrroooggggnnntudjuuuuuu!!!! lol), with the expected disastrous performance dropoff as a result.Ĭould we please maybe perhaps get a core/thread affinity locking feature built right into the client instead? It would seem the best solution to the issue. In this case, we will be adjusting the audiodg.exe process to ensure its using the correct cores and has the optimal priority to prevent any audio related. With Process Lasso you can set CPU affinity and CPU priority to prevent over-usage of the CPU on certain processes. Why is the bloody scheduler still so brainless, after all this time? Process Lasso is a free real-time CPU optimization and automation software. Step 1) Open CS:GO (or any other game - just have it running) Step 2) Open Process Lasso and go to 'Active Processes' Step 3) Choose your game process by right clicking and choose 'CPU Affinity' - or something along those lines.
How to use process lasso for ryzen driver#
I have a newly purchased 7950X3D CPU, with AMD's thread management driver installed, and it seems that CPU folding threads still get bounced around basically randomly amongst the CCDs by the windows task scheduler, something which is generally bad for performance on AMD hardware.
forward with a set of two CS:GO programs, Process Lasso and GameBoostHD.
Perhaps particularly with 12 or 16-core Ryzen 7000-series X3D parts, as the CCD with the stacked 元 cache die is lower clocked than the other CCD in this case (and as we know, CPU folding is always limited to the speed of the lowest performing core.) By simply reallocating the CPU usage from useless background processes to CS:GO. Since 12 and 16 core Ryzen CPUs have dual CCDs/chiplets, is it generally recommended to divide available CPU cores into two CPU folding slots with >16 threads each (multithreading enabled, of course) or not.? Windows 11 OS, by the way.
