Maximum PC

Is there a texture quality/resolution limit when referring back to monitor resolution size?

Example: Skyrim, replacing textures below 2048 or 1024 with some that are 4096. My monitor resolution is 1920x1080.

Does this translate in any way to a maximum quality that can render at that monitor resolution?

Short answer: No.

Long answer: Texture resolution is the size of the texture itself, which gets resized on a polygon. If you had a 1024x1024 texture on a smaller object, it would look crisp and clean. If that object were put on a really tall building, it'd be stretched over and look blurry/muddy, assuming the developer didn't allow for repeating.

However if your video card doesn't have a lot of memory, it won't support higher resolutions (or rather, you'll have graphical glitches). But if you have 1GB or more on the card, then this is less of an issue.

Ok thanks!

Yeah, I have 2x EVGA 580 GTX in SLI, so 1.5 VRAM. I noticed hitching before optimizing textures down a bit though.
