@ManeEvent4U2 Strange, I could have sworn that there were more resolution options than that. I just checked on the mac side, and there are a bunch of 16:10 ratios, but no 5:4. Still, you should be able to change the resolution manually. Again, it's best to use a clean game folder, in case this makes things worse.
Inside the folder, there's an options.ini file. Open it with a text editor; whichever option Windows offers is probably fine. Find the line that lists the screen resolution, and change it to 1280 x 1024, the resolution of your monitor.
If this doesn't help, or makes things worse, delete that options.ini file, load the game again to the Main Menu screen, and put it in windowed mode. Then quit and try the same edit.
I changed the resolution to the amount that you suggested, and I also changed the Refresh Rate to 60, and oddly enough, these changes seemed to help.
However, it didn't stay that way for long.
