At 1080p (Full HD), the AMD Ryzen 5 3600 will hold back the NVIDIA RTX 3090 by roughly 19-26% depending on the game - CPU-heavy titles will feel it most. The processor cannot feed frames to the GPU fast enough, so you may see lower-than-expected frame rates. Upgrading to a faster CPU would unlock the full potential of your NVIDIA RTX 3090.

These are estimates, not benchmarks. Your actual frame rate depends on your exact settings, resolution scaling, drivers, and the scene on screen - treat these as a realistic ballpark at high settings, not a guarantee. Lower settings or upscaling (DLSS/FSR) push them higher; maxed-out ray tracing pushes them lower.
