Hihi still having the same issue ^^
To those also suffering, it seems lowering high spec game quality may help a lot? My pc is good but I think Remix has trouble keeping up, my pngtuber has done the mute thing a lot less since doing this. Although the game qaulity lacks I think its better than being mute for a min and instead more like 10-15 seconds. My I also made his rig more simple to combat the lag a bit? (Idk if this helps tho?) He seems to be just fine is simple low spec games so I'm really thinking it's just Remix being overwhelmed.
