New laptop - massive fps drop with more than one dx11 renderer open

Well that’s exciting:

After double-checking any possible video-related suspect, I just found out that the guilty one was “Nahimic for MSI”, some apparently AUDIO-oriented bloatware. Not where we instinctively pay attention to, but probably some directx involved there, not so surprisingly after all…

Toggling it on and off immediately shows the perf jump; that’s repeatable and systematic, even with laptop reboots in between:
– Nahimic on (process is launched on start up by default): 30 or 60 fps (can’t really spot why/when between the two)
– Nahimic off: 120 fps

Sharing this for any other desperate soul in the future

Peace!
