Hello,

My FPS drops to 0 when me and my friend try to launch a space plane at the same time.

I am running windows 8.1 and the game is installed on the ssd.

Graphics card, CPU?

graphics card is gtx 580 in sli, I tried disabling the sli
cpu is 4790k

Are you using any other mods? If yes, which ones?

We are using FAR and deadly reentry

Probably some of these mods is conflicting. Have you tried removing DMP to see if the issue persists on Singleplayer?

The issue only happens when we both launch at the same time.

It doesn't happen at any other time.

I don't know what's happening then. @godarklight, pinging for him to check the issue.

This can be caused by two things, the first is a DMP hang related to the crew reassignment, the second is a hang when loading the vessel in KSP. At the moment it is a little freezey on full updates - I'll try poking it after work today to see if there is anything we can do.

One more thing that I would like to add, we are using the development version of DMP, not sure if it matters.

I think because you are launching at the same time you end up so close to each other that it consumes alot of cpu to render both players. I have alot of problems when 2 players come close to each other in my multiplayer tests.

Doesn't the "revert" feature record vessel movements to play back on time travel?

Closing this and keeping #298 open
