you are def correct, bright games seem to make the sparkles dissapear
also, the plot thickens… i looked up your PSU. it’s actually on a toggle, it can be single OR multi rail. in multi rail mode it caps each output at 40A. i can’t find stats on the 2080ti founders edition but I vaguely remember reading 2080ti specs ask for 80A? do you still have the box? it might say it on the outside.
here’s where I pulled the info for your PSU.
but if your PSU is definitely in single mode, this would put my theory to bed, in which case i’m hitting Pimax up for a new cable.
edit - here’s an interesting reddit debate on this subject. some say run two 8 pin cables in muti-rail mode. and some say put it in single rail mode so the card can draw as much juice as it wants (overclocked).
Pasting it below because this stuff is WAY over my head. we need a build expert in here.
Again if its a power issue, maybe it’s new to all of us, simply b/c our cards haven’t ever had to work this hard before? Pimax pushing the limits.
Or, it’s as simple as a new DP cable…!
