The game is run on software mode good in notebook video Nvidia GeForce 310M and Home PC video ATI Radeon HD 2600 XT game can work on: Direct3D trid3d.dll not work DirectX6 tridx6.dll work on ATI (only background scene) DirectX7 tridx7.dll (on ATI Only scene) (on NV glitches, full rendering only when subtitles appear, no subtitles no models) OpenGL32 trigl.dll not work, works both in case of use custom opengl32.dll from TitaniumGL -> (only 2012 version) http://nvworld.ru/files/downloads/wrapp ... 201011.zip Models rendering in most high quality but no scene at all =( 3dfx (glide api) triglide.dll not work with nGlide on both ATI and NV i see 3dfx logo after that black screen and returns to windows without any errors/warnings =( other 3dfx wrappers not tested, also i am not sure it work on real 3dfx hardware. found also useful site (warning russian language need translator) http://nvworld.ru/files/old/docs/glide.html The game only works correct on my notebook with 1366x768x32 reslution, everything other is fails. Need some workaround on this game, it uses nocturne engine, probably all Blair Witch games has same problems. If additional files needed i can upload it, like tri*.dll render libraries, i have found while trying fix it, nothing really works. With DXGL it quit unexpectly without any messages.
