NVIDIA and CD Projekt RED recently released the Ray Tracing Overdrive Patch for Cyberpunk 2077. This RT Mode is so heavy that even the RTX 4090 needs DLSS 3 in order to achieve playable framerates at 4K. And while at first glance everything appeared to be working fine, upon further testing we’ve discovered that DLSS 3 is completely broken on the AMD Ryzen 7000 series CPUs.
For our tests, we used an AMD Ryzen 9 7950X3D, 32GB of DDR5 at 6000Mhz, and NVIDIA’s RTX 4090. We also used Windows 10 64-bit, and the GeForce 531.61 driver.
With DLSS 3 Frame Generation, both The Witcher 3 Next-Gen and Cyberpunk 2077 are completely unplayable due to severe stutters. In Cyberpunk 2077, these stutters can occur during cut-scenes or during gameplay. These stutters are so severe that make these two games completely unplayable. We’re talking about 2-3 seconds stutters at single digits framerates.
For those wondering, these stutters were absent on our Intel Core i9 9900K PC system. Yeap, on that dated Intel CPU, we didn’t have any stuttering issues at all when using DLSS 3. And, in case you’re wondering, we are not the only ones experiencing these issues. A lot of owners of AMD Ryzen 7000 series CPUs have reported similar issues. For instance, here is a video showcasing the stuttering issues in The Witcher 3 Next-Gen.
It’s also easy to replicate this issue. Instead of launching CP2077’s benchmark, enable DLSS 3 Frame Generation and start a new game. Then, during the game’s tutorial, you’ll get major stutters, especially when grabbing enemies from behind.
Now the good news here is that DLSS 3 Frame Generation works fine in other titles. For instance, Forza Horizon 5, Microsoft Flight Simulator and Hogwarts Legacy ran smoothly. In these three games, DLSS 3 did not bring any additional stutters. So it appears that this stuttering issue is only affecting games using the REDengine.
All in all, this is a PSA for owners of AMD’s latest CPUs. We’ve already informed NVIDIA about this, so let’s hope that the green team will be able to resolve it sooner than later.
Stay tuned for more!
