If you need guidance on GPUs, there are people who can help. You recently purchased a new 7900 XTX but it's not performing well—benchmarks show it's underpowered compared to its potential. I'm guessing the issue might be related to bottlenecks or driver problems, though I'm not sure. After a clean driver install via DDU, you're using a 1920xCPU setup with 32GB DDR4 3000 RAM. You've replaced the GPU and confirmed cables are secure. Your PSU is Corsair RM850x. While playing Witcher 3, FPS drops to around 34, spiking up to 90 (averaging 41 FPS in AMD logs), regardless of location. Turning off VSync, setting ultra mode, and disabling ray tracing didn't improve things. You're expecting 100–200 FPS but only getting 41. I haven't tried SAM or 4G decoding yet because your ASRock BIOS doesn't list them. I think there might be a way to enable those features during boot that I'm still figuring out. Your thermal readings were normal at 400W, with VRAM and junction temps around 95°C.

You're on a Threadripper 1920x, which is a typical frame rate for that hardware.

This seems to be a performance concern with your CPU and RAM. For the first generation Threadripper, disabling one of the CCDs can improve gaming results. Have your BIOS been updated recently?

Hey, the CPU seems pretty rough. I wasn’t aware of its condition before. It’s not surprising it’s a bit outdated, but it still works.

It's the initial Ryzen model, offering performance similar to a Ryzen 7 1700. You can push it to 3.9/4GHz across all cores (I achieved that on a 1950x), which will boost frame rates, though it remains fairly constrained.

It's similar to turning off a component in a computer, but instead it affects the camera's performance rather than the processor itself.

This approach ensures the CPU manages workloads evenly across the CCD, avoiding efficiency drops from infinite fabric issues.

TR 1920x features two CCDs (Core Complex Die). The delay between them is significant, particularly with the first-gen Ryzen, making it unsuitable for gaming. To enhance gaming performance, switch to Game Mode and disable one CCD using Ryzen Master.
