Also, anyone who uses my overhaul will need a mid to high end PC. A bit lower if you turn off ENB. You can gain FPS by using winter edition (you'll need to download it on authors site, I'll provide a link later) (I get a 3-5 FPS increase with FPS using this, and without ENB, its a 10-15 fps increase)
I also recommend turning off the ENB (keep the files...there is a lot...unless you want to go through each one) if you are low on FPS. I turned off DOF (too annoying anyway) and ambient occulusion (DON'T TURN IT ON...I GET 0-1 FPS WITH IT)...with the ENB active I get 30 FPS on average. You'll need to manually turn those back on in the ENBseries.ini file. Which actually, is a huge improvement over in August when I only had 20 FPS average. I didn't upgrade my PC or anything, but I did update a bunch of drivers. B30 FPS is playable personally for me anyway, my eyes suck
But with it off, I get 40-50 FPS on average. So a big 10-20 FPS increase.
Plus, you need ENB in the overhaul, it comes with ENB boost or whatever it does...helps a lot in a stable game. But ENB itself doesn't need to be active. You can manually turn all the effects off.
My system:
Geforce 660 GTX 2GB (I'm going to upgrade to the new Geforce 970 GTX 4gb at some point...I "should" see a MASSIVE increase in performance)
8 gig DDR3 ram
No SSD drive
Windows 7
i5 3.3 GHz CPU
Probably my CPU limits me quite a bit, but really need a 4gb card for a big skyrim mod list...2gb is a bit not enough, and I probably wouldn't do ANY less even without ENB.
