OK, I know this has most likely been post a 100 times on here but i need to know why this is happening... My Skyrim is extremely choppy on low res, and no mods are installed. I get 20fps at the most. If anybody can help me fix this problem, you have my thanks. PC Specs: AMD A6 5400K dual-core processor AMD Radeon HD 7540D graphics 1TB Hard Drive 6GB DDR3 Memory OS: Windows 10 Home P.S.
