Windows 8.1 Graphic Problems

So I just upgraded to Windows 8.1 and it seems to have been gone fine, for the most part.
The graphic and the general view of the Windows itself is fine and normal. However when I launch a game, any game, (havent noticed this anywhere else) the graphics changes completly and its not what it used to be pre 8.1. Everything goes more dark and more greenish, it looks just wierd. I have no idea how to fix this, any idea?

Another thing, after I updated this I got "windows.old" in C:, can I delete that without a problem?


Thank you in advance

Hey, I appear to have figured it out. I use a NVIDIA card btw.
It appears that Windows 8.1 activated Stereoscopic 3D for some reason, so just go under NVIDIA control panel and deactivate it.

I still would like to know if I can delete the windows.old folder tho

If you upgraded to Windows 8.1 from Windows 8.1 Preview or to Windows RT 8.1 from Windows RT 8.1 Preview, some files used by your previous version of Windows will be left in the Windows.old folder. These files will be automatically removed within a few days, or you can use Disk Cleanup to remove them yourself.

1. Open Control Panel by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Control Panel in the search box, and then tapping or clicking Control Panel.
   
2. In the Control Panel search box, type Admin, tap or click Administrative Tools, and then double-tap or double-click Disk Cleanup.
   
3. If you're prompted to choose a drive, select the drive that you just installed Windows on, and then tap or click OK.
   
4. In the Disk Cleanup dialog, tap or click Clean up system files.
   If you're again prompted to choose a drive, select the drive you just installed Windows on, and then tap or click OK.
   
5. Select the Previous Windows installation(s) check box, and any other check boxes for the files you want to delete, and then tap or click OK.
   
6. In the message that appears, tap or click Delete files
   
   

Thank you, if its gonna be deleted automaticly in a few days Ill just wait and let it handle it itself
