It is indeed a bit faster, however the performance is still far from the old value. I don't see any other way to speed this up the way it's being synced now, the question is however, whether the apps really _should_ modify the bitmap on windows too (don't know whether they would try to draw controls onto the window and then it would be overdrawn by the opengl image; application like Steam are trying to achieve similar, but they seemed to work well before)

Does this very rough&ready patch work any better?

I'm sure it's much faster, problem is it doesn't work. How do we know if the app has fiddled with the dib section bits?
Huw.

Sorry, maybe I should read the patch properly before commenting :-) I assumed that you were setting need_escape to FALSE after sending the escape, but you're not. Indeed it would be interesting to know if this helped.

Heh, you had me a bit worried for a second there! Indeed I do not know what the original patch does or why it's needed, but the slowdown just seems related to looking up the Wine_GLContext and testing it.
If this patch improves performance I'll fix it to use Win32 TLS instead of ELF TLS, it'll be interesting to see if that changes makes a difference too.
