I just tried the DXTweaker as described above in the first post, however I have some issues. I have a GeForce 6600 and running XP.
When I run as described with DXTweaker the Jane's video and all the videos in the campaigns are upside down and very blocky:
Furthermore, the TSH video which comes on after the Jane's one on startup is upside down but NOT blocky:
Everything else in the game *seems* to run fine... However, when I exit the game I get these errors:
Initially I thought this could have something to do with running F18 under Win98-ME compatibility (I run under this compatibility otherwise I cannot hear all sound in the game), but when I tried running f18 undeer Win2000 compatibility mode with DXTweaker all the videos were the right way up BUT looked like this:
And the same error messages appeared after exiting the game.
Could this have anything to do with resolution issues? My desktop resolution is 1280x1024, TSH manager setting is set to "Same as desktop", and my in game resolution setting, under graphics/drivers is 1024x768.
Any other advice or comments appreciated...
