Game is very laggy with any vessel then crashes/black screens.

[Arte]

My game isn't laggy until I put any part in the VAB, then I lag a lot until I remove the part, and if I launch its insanely laggy then the game either black screens like the NaN Kraken or just crashes.

I had a problem like this once and it turned out the problem was Ven's Stock Revamp, but that isn't the case this time.

I made a fresh install and launched with everything stock and had no problems then once I added my mods again I was having issues again.

Unfortunately I don't think there are spoiler tags on the KSP forum so sorry about that.

I am using the 64bit version with the Unfixer but I was having the same issue before with 32bit KSP and ActiveTexture Management on Aggresive, I thought maybe it was a ram issue so I switched to the 64bit version.

[sDaZe]

Hmm... Mind showing me what your memory is at when this starts happening? You may be getting close to your ram limit. Mind telling me how much ram you have as well.

[TheRag]

Well you going to need to post a log, I guess it is related to a NRE flood sounds simliar.

[Enceos]

You could add the Exception Detector mod to your list to find the issue on your own, or could post a log file here. Sudden lags are usually an NRE spam which fills your log to the critical crashing limit.
