Has anyone with a Titan and 6gb of vram said anything about still having stuttering? The problem is most certainly vram. All you have to do is monitor your vram usage on ultra with no mods to see this. Maldo's stutter fix is a mod that removes the mip maps from the textures to reduce the file sizes. That's why it fixes stuttering. It makes the game use less vram. Those with 3gb cards or lower are suffering most. The game can reach 3.7 gb of vram, even though the ultra textures option says you only need 3gb. EDIT: As mentioned above by Plissken, your CPU plays a big role also. Never the less, vram usage is very high in this game and even with the best cpu you would still stutter some from high vram usage if you have a 3gb card.
