Skyrim graphics issues

So my graphics card is a 2GB MSI radeon HD 7850 and I play skyrim on high with about 60 fps. the fps isnt the issue, the issue is that sometimes the backround will just get kind of glitchy. random sections of sky will disappear for a fraction of a second. idk just figured maybe someone might be able to help

Do you have mods? If so, it's probably them. You may have conflicting mods or something like that.

i have the exact same card from the exact same manufactorer that happes to me to i tryed overclocking it i think its just a glitch in the game do you use hdmi or vga


I use vga with no mods, have you found a solution for it?
