The performance of Lyra 5.4 is very bad.
Default everything:
4060 Ti 16GB on 1920x1080: 30-63 FPS in a map that looks like you could easily play it 20 years ago on a GeForce 1.
Most of us thought 5.4 would give automatically improved performance. But you have to trial&error now to get at least the same performance than previously instead creating games. We all know that refacturing could cause issues. But I hope this gets recognized as a: No.
