Thanks, appreciate it.
Perhaps try a cleanup:
- Uninstall S3D
- Check install path of S3D if it actually is completely removed. If not, do manually. (default: C:\Program Files (x86)\skwas for 64-bit or C:\Program Files\skwas for 32-bit)
- Remove all subfolders under %localappdata%\skwas (this is where settings are stored)
- Reinstall S3D
Did it previously work on this system? Are you running the last version of S3D (0.9.9)?
Are you running some tools that modify/monitor/control DirectX like Riva tuner, a 3D screen grabber, etc. (try turning off if you do).
Some tools that monitor and hook DirectX (f.ex. to render an overlay) have been reported to cause issues.
On the flip side, some of these tools could actually maybe solve it, by forcing DirectX to 'not' use anisotrophic and/or antialiasing (which S3D does use if your GPU supports it).
Just some idea's...
