First time I saw it was in the original Unreal game (1998) when using the software renderer. It had this very distinct asymmetric dithering pattern.
Can't find a screenshot of it on short order, seems most screenshots are either of unrelated newer Unreal Engine or use hardware rendering which doesn't show this dithering.
they have their own pain - there are those different mosquitoes, that tries to enter your every orifice. eyes, ears, nose, urethra. very annoying.
after long journey we arrived into the camp. we wondered why we were the only ones there, so we got out of the car and there they were. a lot of them. that was the fastest i ever built a tent and we jumped in it and called it an early night :)
'raccoon on cocaine' she calls it :)
