The 3D editor lags in the Future+ and mobile versions, even if I chose the Wayland platform option. It doesn’t lag only on the “Compatibility” version. When I used the integrated graphics chip, there was no problem.
This is likely because graphics drivers are not set up correctly, as the graphical glitches in the editor indicate you’re using a software rendering Vulkan fallback (llvmpipe).
Try running Godot from the command line and look at the output to see the GPU driver in use.
Your GPU does not have Vulkan support, so please stick to the Compatibility rendering method which uses OpenGL. You can switch rendering methods in the top-right corner of the editor.
llvmpipe allows Forward+/Mobile to run, but it will never run well as it’s software emulation.
I think I know why she knew. The R9 290X supports the Vulkan API up to version 1.2.170, and the photo shows that it needs version 1.3.278. The fact that it worked on the integrated is because it supports this version.
