Have you followed the main S.T.E.P. guide as your resource for mod downloads and the recommended version? If not, and you have a card with a smaller amount of VRAM as is the case here, you're missing out on some proven recommendations for which versions of files to download to ensure that you're not going to max out your VRAM while still gaining benefit from each mod. Normally the S.T.E.P. guide recommendation is 1k vs 2k or larger. If you have installed max resolution versions of many of the larger texture mods, that's the first place to start in order to get your VRAM usage down. If following the Skryim Revisited guide only, you're likely grabbing a lot of textures that are going to add up to be problematic. So first I'd start with ensuring you're using the 1024x1024 versions of many mods, and see how that works. If you're still having issues you can then do additional DDSopt runs on texture replacement mods and do deltas comparisons to see if you're gaining solid optimization which will help as well. The last resort is to just starting picking and choosing which mods you run. Sometimes foregoing a handful of mods is enough to get stable again, others nixing a large mod alone can do it as well. Just have to balance the sacrifice of the selected mods against your game being playable. Thanks for the reply. Kind of thought when i started this guide that as my video card was a GTX670 it was the same as Neo's. Didn't realise to now that i had a 2GB version so to answer your question I was only following the Skyrim Revisited guide. Looks like I'm going to have to go back and grab the 1k versions. When i was doing it i thought the 1k versions were for cards <=1GB. Thanks for the help.Â
