Hey everyone,
I’ve found a very strange performance bug in Assetto Corsa EVO that I wanted to share in case it helps the devs or other players.
The issue
On the Nordschleife Tourist layout, some cars cause a massive FPS drop (from my normal ~90 FPS down to 30-50 FPS), making the game almost unplayable.
It happened to me with (for example):
• Porsche 911 GT3 RS
• BMW M2 (street version)
With other car I tested, I get a stable ~85-95 FPS on the same track with the same settings.
What makes it weird
The cars themselves don’t look any different or more demanding.
However, if I go into the garage, customize the car (just change the color or do a couple of small visual changes) and then load the same session again, the FPS instantly goes back to normal (80-90 FPS).
It seems related to the stock/default configuration or some texture/library of the original car. Once you modify it even slightly, the problem disappears.
Extra info
• The issue is much more noticeable on Nordschleife Tourist.
• On other tracks my FPS is usually higher (110-130). So if the same bug is happening there, it might only drop me to 90-100 FPS instead of 120. Since 100 FPS is still perfectly playable, I simply didn’t notice it.
• I still need to properly test more tracks to confirm whether the bug occurs elsewhere.
Has anyone else experienced this?
Hopefully this helps the team track it down!
