Too 'defined' graphics

@Evil_Mantis14  Do you use Reshade, SweetFX, or any other graphics-effects program?  If so, please try disabling it.  It is strange though that regular fullscreen shows this effect when windowed fullscreen does not.  It would be interesting to see a side-by-side comparison one frame as seen in each mode.

I'd also like to see a dxdiag, just in case there's something else going on.  Please run one and attach it to a post.

If it looks fine in "Windowed" mode but not in "Fullscreen" mode, then you have the two modes set differently.

"Windowed" mode runs the game at whatever resolution and settings you have set up in Windows. Settings in the game are pretty much ignored then.

"Fullscreen" mode runs the game in whatever settings are configured in the game, and whatever the OS is set to is ignored.

If Windowed works but Fullscreen doesn't, then you need to set the GAME to the same settings you already have configured in Windows.

If it works in Windowed mode, I would tend to leave it there.  Windowed mode is only slightly slower than Fullscreen. Plus Fullscreen mode will tend to crash the game if you have a tendency to ALT-TAB out to do something else. Windowed mode won't have that problem.

There are benefits to both. Fullscreen is a little bit faster, plus you can lower the resolution in Fullscreen mode to speed it up even further without it messing up your desktop icon arrangements.

Personally, I tend to do several things at once all the time, so ALT-TABbing out is something I do a lot, and I'd much rather it not crash when I do. Mine's always on Windowed mode.
