Yes, I get the same performance using high textures instead of ultra, with all other options to high. Texture filtering trilinear optimization is on. Also it doesn't matter what type of AA I use, I get the same performance issues. I remember (I posted on Sunset's mod thread, and also PM'd him about a memory leak issue), what happened with his latest version that I installed is that after 01:30 of gameplay , the game was using 15 GB of RAM , and it was crashing of course when reached 16 GB. So that is what I call a memory leak issue. Anyway, I did check RAM usage while using your mod, and I see that RAM reached 8.20 GB, but isn's 8.20GB a bit much for just 1 hour of play? Also, VRAM doesn't cross 2800GB even with Ultra settings, so I don't see any issues there.
