Slowdowns with 60 fps even in singleplayer

[Урал Interceptor]

FPS counter shows constant 60 fps, but the game can go into slight constant slowdown even in singeplayer matches. Sometimes first round can be absolutely fine, but as soon as second round starts game goes into slowdown.
Majority of online matches show ping around 60 and 1 rollback frames. Shouldnt there be more rollback frames if one of the players gets slowdown?
Whats even going on?

Might be a server issue tbh

Try to disable VSync (if you have it on) and put your GPU in maximum performance for the game in the control panel of the GPU.

Slowdown caused by frame rate will instead make the game delay based since game speed is determined by frame rate. Try lowering settings and closing any resource intensive processes

Thanks, it feels that turning on max performance in control panel helped
