Hey guys, I'm currently playing New Vegas with an ENB (It doesn't matter which) and my FPS drops to like 40-50 average. My GTX 660 Ti SLI should get performances similar to a GTX 970 if the game supports SLI. I checked my GPU power and usage % using MSI afterburner and both GPU's were at only around 60% usage. CPU doesn't max either, and I made sure to turn off AA, AF, and Water Displacement in the launcher settings. Are ENB's really just THAT demanding? Or is there something wrong on my end? EDIT: I forgot to point out my other specs: i7 3770K, 16GB RAM
