I have the ENBSeries working, but I'm trying to have it optimized for my ATI X1300 Graphics Card, videoram 256MB.
System Ram is 1GB.
I tried the "preset" configuration for the X1300, posted by cDa, and it caused my FPS to drop down from 20-25 to 15fps, even with "Frame Limiter" off. I tried to scale it down, and it's still the same FPS.
I have Water and Shadow off, and toned down the Bloom, and the Reflections a bit, and it's still not helping my FPS.
