8GiB (8GiB per node)Ī few months later, I bought two copies of Far Cry 5 (FC5) for co-op and was determined to make it work on my system. Maybe with a 2950/1950x I’d feel better about it, because I need those 16 threads.
PROCESS LASSO 1950X FULL
I didn’t bother with isolcpu because I need full bandwidth in the host, which is rough on a 1900x.

When investigating stutters in GTA V performance, I limited Windows into NUMA zone 1 and decided to stick with that configuration NUMA zone 0 seemed to contend more frequently with host processes. BackgroundĪs I mentioned in earlier posts, my original VFIO setup exposed two NUMA nodes to the host Linux kernel with proper CPU mappings for each: 16GiB (8GiB per node) See “Related Articles” for a link to the last article where I distributed these patches.

I don't know if it's the optimization, or BIOS handling the RAM latency differently in UMA mode, or by design, but this really doesn't feel like a $1,000 CPU experience I was hoping for. I'm reading through forums and almost everyone who's using TR 1950x as a streaming + gaming are having the same issues. Setting CPU affinity using Process Lasso per game / app - Very inconvenient, meaning optimizing each of them by monitoring. If I want to use creation tools such as Adobe or programming / DAW / compiling, I have to set it back to Distributed mode, meaning a reboot.ģ. I wouldn't feel safe until I change my RAM size to 64 or 128GB.Ģ. I have to monitor and make sure that apps don't go over 16GB. Local mode only works in tight latency in HALF of the RAM - I have total of 32GB, but with Local mode, each TR die gets low latency access to 16GB each, meaning that any applications going over 16GB, it's gonna introduce the higher latency stuttering. This introduces too many inconveniences:ġ.

So setting my PC to Local mode + Process Lasso seems to be a solution, right? Playing Overwatch + OBS Streaming (960p) in ANY CPU preset or resolution will introduce Stutter / FPS drop issue.īUT when I try the Local mode (NUMA), things have gotten much better, especially when I set the certain processors via Process Lasso. It's not GPU loading issue checked with GPU-Z. I tried both non-OC and OC makes no difference. It's not a temperature throttle Tdie is under 68C. I believed that Distributed mode (UMA) was good for contents creation, so that was the mode I tested. Memory: Corsair Vengeance LPX 32GB 3000MHz
