Symptoms

Multiplayer matches have low and unstable FPS, ranging between about 30 and 45. Graphics settings did not appear to have any effect on this: the problem occurs even with the graphics turned as low as they will go.

Offline matches with the same characters on the same stages run at a stable 60 FPS, and the open beta of the game did not have this issue either.

Reproduction

1. Join any online multiplayer match.
2. Issue should occur every time.

Start by reproducing an online multiplayer match with Proton Experimental 8.0-20230531 and review the attached steam-1364780.log alongside the reported system information. Compare online performance with the stable 60 FPS offline case; done means identifying a supported cause and confirming that multiplayer matches no longer show the reported 30–45 FPS instability.
