There was a similar issue before that seemed to be resolved, if its the same as in this thread viewtopic.php?f=4&t=56, You could try launching 4DO with the argument --forcegdirendering and see if it still happens.

Well, you've got choices, you can try "smooth image resizing", or change the scaling to Double resolution rendering, or try a HQ filter, all under display in the menu bar.

It should list your CD Drives under the File Menu, after Close Game and Open CD Image File, there should be Open Disc Drive options with letters of your various CD Drives.

Yeah, none of the scaling mode's make any difference, same with double resolution rendering/smooth image resizing. The screenshot's just got the fps counter in the bottom right, so you can tell where Fraps thinks the bottom right of the window actually is, changing the counter to display in the top ...

Or just do that :) BryWI Something I noticed when trying to record from 4DO with Fraps was that it only recognises the top-left portion of the screen, I don't know whether to post that in the Beta forum or the General forum, I'm not even sure if the problem lies with SlimDX or Fraps. The attached sc...
