I recently changed my graphics card from an AMD 5850 2GB to an NVidia 750 Ti 2GB. Roughly the same performance, much less power and heat consumed. It's been doing well overall, in this secondary PC.
RO doesn't seem to be giving me the same good fortune. I'm seeing a good deal of jagged sprites, and certain portions of maps exhibit strange black squares. The UI elements are normal. It's just the textures and sprites.
Perhaps someone has seen this before, and might know what could be changed. I've tinkered with the Setup.exe (run as administrator), compatibility modes, and toyed with the Nvidia control panel. Driver version is 344.75. Was working fine with AMD drivers 13.9 and 14.X.
Here's a screenshot, for examination.
