Network game is stuttering with uncapped framerate on

[Meerschweinmann]

Hello.

When i start a multiplayer game with PrBoom-plus 2.6.2 over LAN and turn uncapped framerate on it stutters extremely on both PCs.
If we turn uncapped framerate off the stutter disappers, but then we have only the original 35FPS.
V-Sync, Software mode/OpenGL or other screen-resolutions doesn't change anything to avoid this judder.

In Single-Player mode everything is fine with uncapped framerate on.
