I use texture anti-aliasing in User mode, but I usually use it there. The settings I used were 4, 10 and 33%. The up and down rod-like lines had appeared on the procedural terrain and were biproducts of a mat that added green slime near the water, but somehow appeared weird on the right. Since I could not get rid of them and liked them on the rest of the terrain, I decided to cover them up. The part that baffles me is why did the ecosystem of foliage that I placed on the water in front of the terrain and the three bushes that were also placed in front of the procedural terrain, move in the user mode rendering.

I'm not sure tech support will be interested in an older beta problem. The newest doesn't work well for me. This one seemed OK until now. I'm going back to 292210. I'm on XP 64 with 4 gig memory.
