@Gagaryn between high and ultra I'm not sure. I really only noticed a gain in performance when switching from high to low. At the time I was only concerned in the resulting frametimes and in that respect there was a measurable improvement. Visually though, from memory at least, you don't see much of a difference from one setting to another. I think graphics settings need to be looked at generally there are some definite inconsistencies, but I've only really started testing since the most recent update so I might not notice something that was working previously. @0ct0 That's so weird, Spa is a big track but I didn't feel it was much more demanding that any other I think in terms of optimization it and Nords have probably gotten the most love as they're big names. Just out of curiosity what happens if you crank up the ingame settings and SS at Spa also how does Nords preform? The only thing I noticed about Spa was between 20:00 and 06:00 its a no go for me at the settings I would like to use. Which is the case for pretty much all tracks I've tried. I think car detail levels are working ok, at least for GT1s they look decidedly box at low. Maybe this isn't true for every car though.
