I'm running a 560TI with 1 gig of video memory. When the game came out I had those mysteriously low-res textures even though it defaulted to Ultra on the settings. When I looked, I discovered that it had downgraded the settings, so I changed it and ticked that checkbox. I have not had a problem since, though I have learned that my rig cannot handle 10,000 men on the field at once. For me, 4-5000 on the battlefield doesn't cause any problems.
