Yeah, I did, but I couldnt really see any difference (probably because my load order was messed up resulting in pixelated reflections, maybe it works better now)? Anyway, heres someone on the Nexus who seems to think that higher values gives "lower quality" and in order to get the best result you should use iReflectionResolutionDivider=1? I have no idea whats best here so Im keeping iReflectionResolutionDivider=2 for now...
"Since you're into reflections check out this skyrimprefs tweak:
iReflectionResolutionDivider=1
Setting it to 1 means your reflection quality is equal to game quality. Higher numbers lower the quality of reflections. I haven't checked with your mod but it just might affect object reflections. I tried it on water and it's really a big improvement.:"
