Hi all (:
im new to linux and set up manjaro with a vfio vm.
i use a 3600 with 32gb and an 6800xt. (wx3200 for linux host)
i cant get jack to work but everything else looks like its working.
i followed the arch wiki in addition to the looking glass wiki.
also a few blogs for performance tuning like hugepages hyperv etc to get windows sandboxing etc to work.
sadly looking glass breaks with hdr and it also looks really washed out and bright compared to the direct output.
but now to my question / problem:
i tried a few benchmarks and the first test looks promising
sadly when i tried my first game i quickly noticed that gaming is not possible
the mouse which is passed through spice is super laggy and stutters as soon as there is a little game running (tested with deep rock galactic)
you can also see the lags in normal windows:
is there any solution to get looking glass at leas some what playable for shooters?
for those interested here is my current XML ( i will provide any information i can if you want it: )
