Am I the only one experiencing the problem of a grain graphics ?

the graphic was ok when I had the high resolution texture pack, but after I removed it (bsa+esp of the three packs) I noticed that the graphic is kinda grainy. Maybe is just me? I'm running the game on ultra.

I've got a stamp:

Suggestions ?
And also, is hdtp worth it?

Try turning off anti-aliasing in the skyrim launcher/options.

No, don't use the hdtp, but don't delete it either as steam will redownload it.

Use 2k full or light instead (or along with it if you like)-I use 2k light on my laptop, no hdtp, and some face/body mods to fix the face issues like blocky noses when not using the hdtp. You will have better textures and less vram usage.

And go ahead and pop in some lighting mods while your at it.
