Bad performance in Windows 7 (v0.3.1) #120

Hey, so im running Windows 7 64 bits and have a few old games that run on directx 7 they have fine performance by default (some needed some tweaks, some didn't) but i wanted to try your wrapper to see if i could get better performance. I tried it on RealMyst and Alien versus Predator 2 but with it, the performance is just awful, the game is running at like 2 fps Im running all my games in exclusive fullscree

im adding my avp2 log, dunno if u need it DDrawCompat-lithtech.log n

This is a known issue for Windows Vista/7 since v0.3.0. I don't have a proper solution yet, but you could try the quick fix attached in this comment to see if it helps: https://github.com/narzoul/DDrawCompat/issues/104#issuecomment-869168178

Yes this fixed the performance issue, thx seems to work flawless on AVP2

i noticed some graphical glithces on realMyst running in T&L HAL mode regular HAL mode seems to work fine so nothing important i guess

The Windows 7 performance issues have been fixed in v0.4.0.
