RTX 4070: Performance Issues and Graphical Artifacts in Minecraft 1.21.1

[SwiftKnight270]

I’m experiencing issues when playing Minecraft 1.21.1 with an NVIDIA RTX 3080. The game shows strange graphical artifacts, inconsistent performance, and occasional crashes when enabling ray tracing or shaders. Are there specific NVIDIA Control Panel settings that could fix this?

I don't know, that sounds like video card issues.

1. Make sure your card is clean and not clogged up with dust; you don't want it running hot.
2. Check your drives, make sure their up to date.
3. Shut down your computer and make sure your graphics card is seated properly.
4. Ensure you're running an adequate power supply.

Beyond that, I can't think of what else to check for.

Good luck

Thanks for the reply, that actually makes a lot of sense. I’m starting to think it might be a system issue too, because I’m getting the same kind of problem in Roblox when I turn on ray tracing. Like, in https://playbloxfruits.com/ the graphics start glitching out, and sometimes it crashes randomly. Do you think tweaking stuff in the NVIDIA Control Panel, like limiting FPS or messing with those advanced settings, could fix it?

Actually, the card itself may function well, it may be the Ray Tracing Cores causing you issues.

I found a discussion on Toms Hardware about a user experiencing similar issues with a 3070.

They suggest a larger power supply, swapping drivers and a few other things. Eventually though the conclusion was RMA as they believed it to be a hardware issue.
