I have a high performance machine similar to your top-rated slider machine, but I found the MGE XE options kinda... inadequate? There's SO MUCH more pretty to be had.
A couple things I did to make an even bigger visual difference with little performance impact:
Performance Increases:
1. AF from 16x to 8x (no visual difference, performance increase)
2. Caustics from 80 (!) to 35 (looks more realistic, might save a frame or two)
3. Draw Distance from 20 (!) to 9 cells. (you can't normally see past 12 cells normally anyway, and 9 is a nice performance compromise for the following...)
Visual Quality Increases:
1. Fog mode from Depth Pixel to Range Vertex (very little performance ding, noticeable improved fog quality)
2. Distant Statics- Near [100] end [2.5]; Far [400] end [5]; Very Far [600] end [9] (Big difference in in-game shadows, density. Fairly large FPS hit. Distance past statics is pointless.)
3. Fog- Start [1] end [8.9]
Misc
1. Checked Responsive menu caching
2. Allow screenshots check is pointless with MGE's screenshot capability. I unchecked it.
Maybe useful for an ultra-high setting? The Performance increases, in any case, could help some of those guys on the border with the high-end slider setting.
edit:
I figured I better post my machine so you can compare.
CPU: i5 2500k @ 4.4GHz
VGA: GTX570 @ 870/ 1975
RAM: 8Gb DDR3
HDD: Samsung 470 SSD
I am getting 25-50 FPS with about 100 additional mods and a pretty heavy MGSO install.
I just added your settings works well for me. Thanks for the tips. Incidentally...I couldn't find the fog setting?
>>>>THIS: Fog mode from Depth Pixel to Range Vertex (very little performance ding, noticeable improved fog quality)
Also I'd like to pull in the fog distance a bit seeing Vivec from Seyda Neen makes it look kind of small. Suggestions what to alter.
Thanks in advance!
