Hi and welcome,
No don’t know any mod for this, but maybe someone else could help you find one.
You probably own a Nvidia?
I too have some occasional visual glitch when looking at fires, mainly with UZO or binoculars.
Nvidia isn’t top for SH5 anyway, because ATI owners seem to get less troubles...
But have to say since i’m Playing on my native resolution 2560X1440 i have less troubles of that kind.
Of course had to activate the appropriate TWOS mod for resolution (in TWOS parts)
