DLSS made my GPU feel new, but it revealed a CPU problem I didn't know I had
The article highlights the impact of Nvidia's DLSS technology on gaming, illustrating how it enhances performance and makes older GPUs feel like new. However, it also exposes potential CPU bottlenecks, particularly when running at lower resolutions. The author reflects on their experience with an RTX 4090 GPU paired with a Ryzen 5800X3D CPU, revealing how enabling DLSS can reveal performance limitations not initially recognized. This rings especially true at higher refresh rates, where the CPU's performance may not match that of the GPU, leading to visible performance dips and stutters.

TL;DR
- DLSS has improved the perceived age of the RTX 4090 GPU.
- The author experienced less noticeable performance issues at 4K compared to 1440p.
- CPU bottlenecks became apparent through high refresh rate gameplay.
- Frame generation doesn't eliminate stutters caused by CPU limitations.
- The author ended up upgrading to a 9800X3D for better performance.
Interesting facts
- DLSS can make older GPUs feel newer but exposes CPU weaknesses.
- At lower render resolutions, CPU performance is crucial for maintaining high frame rates.
- Frame generation may create the illusion of higher FPS but doesn't solve underlying stuttering issues.
