4.0 has some kind of GPU memory usage issue. In a clean install with just KS3P (default config) entering the game, going to another scene, waiting a while, and then back to KSC results in my GPU's memory quickly filling to maximum. (As mesured by MSI Afterburner) Sometimes this crashes the game immediately, other times I can play for a while with bad stuttering before a crash.T
This does not occur in previous versions of the mod where memory usage isn't even a third of the maximum achieved here. If there's anything I can do to help narrow down the issue let me know.
