- The RTX 4090 cannot maintain 60fps at 4K Ultra/DLSS Performance/RT Ultra (base 1080p resolution). It runs at 45-55fps. GPU usage is around 45-50%.
- The RTX 4090 at 4K Ultra/RT off managed 80-90fps range but GPU usage was still low at around 50-60%
- A 3060 Ti on the same system at 1440p Ultra/No RT ran at 45-55fps but with stutters that did not seem to be caused by shader compilations (VRAM perhaps?), However, GPU usage was consistently at 95%+
- The 3060 Ti at 1440p Ultra/DLSS Quality (base 961p resolution) ran at 70-80fps but notably, GPU usage dropped to being almost always below 90%
- The 3060 Ti at 1440p/Medium ran at around 70-80fps but once again, the GPU usage was quite low, often dropping to the low 80s
- The 3060 Ti at 1080p Medium ran at 85-95fps but the GPU usage dropped even further, often hovering around 70-80%
- The 6700 XT at 1440p Ultra/No RT ran at 60-70fps, notably, GPU usage was almost maxed out at 100%
- The 6700 XT at 1440p Ultra/No RT FSR Quality (base 960p resolution) ran at 90-100fps and again, the GPU was almost always maxed out
- The 6700 XT at 1080p Ultra/ No RT ran at around 80-90fps. GPU usage hovered around 100%
- The 7900 XTX at 4K/Ultra/RT off managed 70-80fps. 100% GPU usage
- The 7900 XTX at 4K/Ultra/RT off FSR Quality (base 1440 resolution) off managed 100-110fps. 100% GPU usage
- The 7900 XTX at 4K/Ultra/Ultra RT could not maintain 30fps, tanks to the mid 20s. 100% GPU usage
- The 7900 XTX at 4K/Ultra/Low RT managed 35-45fps. 100% GPU usage
- The 7900 XTX at 4K/Ultra/Low RT/DLSS Quality managed 60-70fps. 100% GPU usage
- The 7900 XTXT at 4K/Ultra/Ultra RT/DLSS Quality managed 45-55fps. 100% GPU usage
Oof, sorry for the long list of bullet points but the tl;dr is that the 3060 Ti and 4090 struggle to be properly utilized. The 4090 especially has extremely low usage to the point of being outperformed by a 7900 XTX without RT. The 6700 XTX and 7900 XTX exhibit no such problem and consistently outperform their NVIDIA counterparts at similar settings and resolutions.
