Linux wayland nvidia - high cpu usage when starting game

So I have it recognizing vk_wayland but when I load a game I have high cpu usage like it's not using the gpu for vulkan rendering. Using the bsnes hd core.

Same problem with glcore

Start by reproducing the high CPU usage on Linux Wayland with an NVIDIA GPU, using the bsnes HD core and comparing the reported Vulkan and glcore paths. Check whether GPU rendering is actually used and document a fix or confirmed cause, then verify that CPU usage improves while the game runs.
