Billy, for SGSSA to work properly, it has to match the MSAA factor, so if you're using 4xMSAA, you will need to use 4xSGSSA, if you don't it can cause blurring.
Thanks, Blkout, for your suggestions on this.
I had had the settings at 4xMS and 2xSGSS. After reading your recommendation I tried 4xMS and 4xSGSS but the performance was quite a lot worse (losing 20% or 30% of my fps). So I've put it back at 4xMS and 2xSGSS (and, as far as I can see, there's no blurring at those settings). I appreciate the tips from you though.
In fact, I'm quite happy with the picture and fps that I'm getting but it's always worth seeing if you can get even better.
I am, however, getting quite a bit of micro-stuttering on some tracks. If you had any tips on remedying that, they'd be most welcome.
BTW, I know about this tip (from Reiza's Formula Truck 1.25 update post re the .PLR, file):
Shadow Updates="127" // Static shadow updates per frame (Shadow Updates * Sky Update Frames should exceed number of static shadows on track)
Sky Update Frames="8" // Frames between sky and light updates
Change it to:
Shadow Updates="8" // Static shadow updates per frame (Shadow Updates * Sky Update Frames should exceed number of static shadows on track)
Sky Update Frames="150" // Frames between sky and light updates
I'm wondering if the micro-stuttering is because of the added (since 1.25) time progression. In GSCE turning off time reduces/eliminates micro-stuttering. But I can't find any way to turn off time progression in Formula Truck.
