Mode: ALL Mode: Dedicated Server Only MODIFIED PLAYFIELDS: No Reproducibility: Always using Geforce 1080, and 2080 whe encounter aplayer Severity: Major DESCRIPTION I have a dedicated server, and play, in the same pc since version 6.x without problems. Since Alpha 12.x, the game play at 60FPS (using vsync) BUT when I'm alone. If someone enter the dedicated server, and I walk toward him from far to close, every the FPS drops TO 1 or 2, and the it goes back to 60 using Geforce 1080 AND 2080. NO RELATED TO CONSTANT 12 FPS like on RADEON And every time someone open the TAB menu, the FPS goes to ZERO for 1 or 2 seconds, and then goes to 60 again. ITS UNPLAYABLE since every patch from ALPHA 12. I TRIED to setup all the graphics option to MINIMUM and MAXIMUM, with the same results! Tested versions Alpha 11.5: PERFECT, no performance issues on any player Alpha 12.0.1: cannot play, due to FPS issue Alpha 12.1: cannot play, due to FPS issue Alpha 12.2.1: cannot play, due to FPS issue Alpha 12.3.x: cannot play, due to FPS issue Stable 1.3.3: cannot play, due to FPS issue Stable 1.5.2+:cannot play, due to FPS issue Stable 1.7.4+:cannot play, due to FPS issue HOW TO REPRODUCE ALWAYS: Run dedicated server or multiplayer on the same PC Enter ALONE Fly all over the place: PERFECT FPS Let a friend enter the game. Every player have a "sphere" of 10-15 mts. Now, every time I go inside that sphere, the FPS goes to ZERO for a second, and the FPS counter display 30 because the drop down is so quick, but VERY noticeable drop to a total freeze.
