I figured it out to play TES IV Oblivion very descent with my old Nvidia 9500 GT, forgot about ENBoost also worked for TES IV..., for real that stuff worths a lot, is not an ENB but uses the engine (main core stuff) of the developer of the ENBs, in simple that engine stuff lets use the ram of your PC on TES games, before using it I could not run the game at 1600x900 screensize without get low fps, now I can :D. Also makes the game very stable. By the way that image just have a small filter of photoshop.
