Last Wednesday, I installed the new macOS Catalina and since then, ONI is severely broken (see image below).
The picture first let me think of a GPU failure. However, no other Steam game shows this behavior, neither does the Heaven Benchmark on Preset extreme (It runs below 20 fps, but it definitely should stress the GPU enough to show any hardware failure).
Geekbench also runs fine (CPU, as well as GPU computation).
I am running macOS Catalina 10.15 on a MacBook Pro 2017 with an i7-7820HQ, Radeon 560 4GB, and 16GB DDR3 RAM.
It’s the latest steam version as well as the latest ONI version. Both were freshly installed after the OS update.
Help! I had an accident and broke my wrist and ONI is one of the very few things I can do
