Question Ray-traced reflections pixelated and noisy with RTX 3060 Ti ?

[Visashi]

Reflections and glass refraction are very pixelated with RTX enabled. Getting this in other games also.
Tried:

• driver rollback,
• different card,
• different Windows

Screenies from q2RTX.

Don't know about other games, but QUAKE 2 RTX uses "Path Tracing" which can produce a lot of noise sometimes. That's the downside of PATH Tracing. Path tracing uses monte-carlo sampling and thus noise is inevitable, at least for now.

This occurs when a pixel isn’t sampled enough times to account for every possible light path that might affect it. The only way to reduce the noise side effect is by calculating more samples, and that has a pretty big impact on overall performance, especially since we’re talking about real-time rendering here.

Denoising algorithms such as Neural Network based denoising, bilateral filtering also help with noise. However, the convergence speed in path tracing makes this strategy very costly. This noise can also be mostly caused by the indirect illumination reflected diffusely.

FWIW, Path Tracing is much more demanding than traditional Ray-tracing/RTX.

Sadly, in a somewhat ironic turn of events, NVIDIA's prized Deep Learning Super Sampling cannot be added to Quake 2 RTX, because of the GPL license used by Quake, as confirmed by developer AlexP on the Quake II RTX Steam forum. Not sure if anything has changed in between though, since I'm not up to date on this matter.

But Intel's AI-powered image reconstruction technology XESS, could be added to Quake II RTX, though, since it is open source, and so is FSR.

Anyway, first provide FULL PC specs. Which other RTX games are you playing ?

Full specs:

ASUS Prime A320M-K mobo, 16gb ram, ryzen 5 5600, rxt 3060ti.​

Thanks for the reply!
Games that i experience the same issues:
Spiderman remastered, Control, Battlefield V on Water reflections, Hitman 3 on water reflections. So far most games show pixelated reflections but oddly the Bright rtx benchmark looks completely fine.

Which Power supply are you using actually ?

Im using a 800w cooler master

I read on a forum that ray tracing in Hitman 3 is actually broken, and it also tanks the performance a lot. Ray tracing is badly implemented in this game, and in some areas the game looks worse with RTX.

Try playing ALL the games without any RTX enabled features, and then compare the visual quality. Can't comment about other games in your list though.
