Same issue after switching to Nvidia gpu and attempting to use rtx in vr on Oculus Rift. Drivers, Windows 11, Minecraft windows edition are all fully updated.
Issue starts after ~5-10 minutes of playtime at which point gpu 3d performance starts switching from 100% to ~3% about every second (while rtx is on) (3d performance stays normal when rtx is off). Keyboard takes about 10 seconds to respond to inputs and outputs are messed up. Issue persists ~5 minutes after closing game. Issue doesn't appear in any official/sponsored server this may be due to the frequent server changes.
Issue ONLY affects keyboard.
I have attempted: Restarting game and pc. Reinstalling game entirely. Changing 3d settings in Nvidia control panel. Troubleshooting keyboard, Windows store apps and Minecraft. Repairing Minecraft using the Windows 11 repair function. Changing from using full screen to windowed. Turning off vsync. Capping framerate to 40.
Minecraft bedrock alongside 1 other rtx bug is currently fully unplayable for me.
