Just watched the DF video.
As others theorized early on we are indeed running into CPU bottlenecks in many games, even at native 4k - I suspect Ryzen 70003D may eventually replace DF's 12900k as their GPU stress-tester if it lives up to its promise. The fact that it's
so fast that it's actually inducing
stuttering due to the CPU not being able to keep up was not something I necessarily expected, kudos to DF for highlighting this. I would never expect 100% increase over 3090ti, but it's actually able to reach 80-100% over the regular 3090 in even a few games is still impressive, especially considering main VRAM bandwidth has barely changed.
With Samsung's upcoming GDDR7 it doesn't look like we'll be hitting a performance wall due to bandwidth anytime soon, so that's good.
DLSS3 though? Well we need to see Alex's in-depth video on this for sure as this was barely touched upon. But damn, those are some pretty huge caveats at this early stage. The inability to cap the frame rate, and the early 'solution' to this by forcing vsync through the CP potentially adding lag too is...not great. When you combine that inability to cap the framerate with the aforementioned stuttering issue when the CPU is being overloaded - which it definitely will be when the framerate is uncapped - and that DLSS can potentially end up magnifying poor frametimes to boot, I'm actually somewhat surprised it shipped in this state.
DLSS3's garbage-in-garbage-out also may put a crimp in the argument that DLSS3 will be the only way to bring 'true' next-gen games at 60+ fps that wouldn't be possible otherwise, it really doesn't look like having anything less than at least a solid 60fps before DLSS3 kicks in will provide anything approaching a good experience, and I'm not even talking about latency. Again it's early, and we'll see with Alex's video, but those are concerning issues. I could also pick up some rather prominent artifacts in some games without pausing the video, in Cyberpunk in particular the power lines had very prominent breakup with DLSS performance and additional artifacts with DLSS3. This isn't necessarily a huge knock against DLSS3 itself as I get that a 60fps video is not presenting it in its more likely real-world use case where it will be employed for 120+ fps , but like I mentioned before, DLSS2 in Performance mode just isn't close enough to native 4K for me to consider it a viable replacement like DF seems to believe. The fact that DLSS3's frames may have negligible additional artificing over DLSS2 Performance mode frames isn't so much a concern for me, it's that DLSS Performance frames are the starting point.
