Hey, congratulations for the launch of version 1.2, great improvements on atmosphere and sounds (they make it even more immersive now).

I saw your post regarding the graphical effects on performance and wanted to add this from my findings: with "Good quality" preset and "Reflections" turned "off" I get fireflies on the edges of the passenger seats, sometimes with flashing white squares around them. Same effect is visible from the helicopter cameras and also on the incoming trains (from the opposite direction). Frame rate tanks a bit when I rotate my camera to look at them specifically (60 to 40-30). I'm attaching an image in case my description is lacking.

I know you mentioned you haven't optimised it yet, hoping this will be of some aid when you get there. All the best ! :D

Thanks! I've sometimes noticed the fireflys on my own machine as well, but not recently, so I thought the issue had somehow resolved itself, but apparently not. It's probably the bloom effect? There might some very small or degenerate triangles in the places where the fireflys occur, will need to investigate and come up with a fix to the next update.

Did a test with "Bloom" setting "Off" and the artefacts are still there for me, maybe there are some inverted normals or overlaps in the mesh. LE: They go away if I turn High Dynamic Range "Off" when having Reflections disabled.

Thanks, I tried the same and indeed, it's not the bloom. They also go away if I enable TAA or disable AO, so it must be a combination of the post effects and how they handle triangle or normal vector edge cases.
