What should I do?
Damnit, I forgot to mention it's Fallout 1 I'm talking about in the title. If a moderator could add that I would appreciate it.
I had forgotten that the .exe was overwritten during that TeamX patch 1.2 (I don't know why there's 1.2 and 1.3.5 in the mod thread here but the latter didn't have a .exe) so I changed to the the GOG one and now the mouse was perfect but due to the change of name on ddraw.dll colours were weird. I changed that back and now the mouse is weird again. :(
If I use GOG's exe, checked OS option and ddraw.exe the mouse seems to be emulated as the original game meaning it's laggy but not as extreme as I had first. However, if I change the name of ddraw.dll the mouse is perfect, it's like a modern game without neither mouse acceleration or smoothing but the damn colours become like artifacts. Is there any way to avoid that?
Windows 7 64-bit if that changes anything.
