I wonder what's the core issue. Probably not it, but I've found that no Event Tracing support is there in wine (maybe I'm wrong) - so no .etw data from neither of the 3 or was it 4 apis to emit these. Just pointing out that sometimes missing one feature, not critical for games specifically, might be critical for another new system, and without it it might not function correctly. Again pure hypothesis. I'm curious though what it is...
