So I did a fresh install of Oblivion today, and I'm trying to figure out what to use for lighting. Here's my system specs:

Windows 7 64-bit

CPU: Intel Quad-Core Q8300 @2.50 GHz

6 GB RAM

GPU: Radeon HD 5570

1 GB usable VRAM

My FPS in vanilla Oblivion can go anywhere from 30 to 60 on completely maxed settings using HDR and at 1920x1080, dropping lower in towns and staying high in interiors and in the wilderness. Strangely, dropping my resolution seems to also drop my FPS by almost 10 frames. I get stutters that drop me down to 20-25, so I might try using the stutter remover and see if that helps. I haven't added in any mods yet, but I'm planning on using QTP3 Redimized, All Natural, Better Cities, Unique Landscapes, Cities Alive at Night, and an LOD replacer (maybe Qarl's?).

So what are my best options? Do I have a chance at running any ENBs? I used OBGE before and to be honest, I wasn't super impressed because I'm wanting something that alters the colors a little more. Which one has better performance? I want to try my best to keep my game at 30 fps and not much lower, even if that means dropping the ingame options a little.
