The video tutorial explains how to optimize gaming performance on multi-CCD processors like the 9950X3D by adjusting BIOS settings and using Process Lasso to assign games like Star Citizen exclusively to the CCD with V-cache, reducing stutter and improving FPS. It also demonstrates managing other applications to run on the non-cache CCD, ensuring smoother gameplay and better CPU resource allocation.
The video tutorial focuses on optimizing gaming performance, specifically for Star Citizen and other games, using Process Lasso on newer generation processors like the 9950X3D with two CCDs (Core Complex Dies). The presenter explains that Windows’ default scheduler sometimes switches game processes between CCDs, causing lag and stuttering because only one CCD (CCD0) has the V-cache. This switching can degrade performance, especially in CPU-intensive games like Star Citizen, which are not well optimized and heavily tax the processor.
To address this, the presenter guides viewers through BIOS settings adjustments to prioritize running all applications on CCD1 (without cache) and reserving CCD0 (with cache) exclusively for gaming. He demonstrates how to navigate an MSI BIOS to locate and configure settings such as AMD CBS SMT options and CPPC dynamic preferred cores to “frequency.” Additionally, he recommends enabling RAM profiles like Expo and adjusting Precision Boost Overdrive settings for improved CPU performance and thermals, although these steps are optional.
Returning to Windows, the presenter introduces Process Lasso, a tool that allows users to assign CPU affinity for individual processes. He explains how to create CPU sets for CCD0 (with cache) and CCD1 (without cache) and how to assign games like Star Citizen to run exclusively on CCD0. This ensures that the game benefits from the V-cache and prevents the Windows scheduler from moving it to the less optimal CCD1, thereby reducing stuttering and improving frame rates.
The tutorial also covers managing other applications, such as Chrome, by assigning them to CCD1 to keep them from interfering with gaming performance on CCD0. This segregation of workloads between the two CCDs helps maintain smoother gameplay and better overall system responsiveness. The presenter emphasizes not to change the CPU affinity of the Star Citizen launcher itself, only the game executable, to avoid issues.
In conclusion, by combining BIOS tweaks and Process Lasso settings, gamers with compatible CPUs can significantly reduce stuttering and boost FPS in Star Citizen and other demanding games. The presenter invites viewers to try the method, share their results in the comments, and support his channel. This setup provides a practical solution to optimize CPU resource allocation and enhance gaming experiences on modern multi-CCD processors.
