EXTREMELY Poor Performance with Parallax

[sciencecompliance]

After installing Parallax v. 2.0.4 to KSP v. 1.12.3 with CKAN v. 1.31.0, I'm getting EXTREMELY bad performance.  The frame rate drops to a literal slideshow with an FPS < 1.

My computer runs other games and base KSP or KSP with EVE perfectly fine.  I have a Ryzen 7 5800x CPU, and an RTX 3080.

I see people with worse system specs run Parallax perfectly fine-ish.  I have new-ish drivers downloaded in the last couple of months for my GPU.

I have tried installing multiple times and have deleted all other mods except for those on which Parallax is dependent.  What the hell could be going wrong?

 

Edit:  Just performed a benchmark test with the free version of the 3DMark software, and my PC performed lower than average but within what appeared to be 1 standard deviation of the mean result for similar systems, and better than 85% of all systems tested using the software.

Performance degradation that extreme is probably due to an exception repeatedly being thrown. Post (a link to) your log files, see guide below, but if the logs are several megabytes in size then it’s a big giveaway that they’ll be full of exceptions.

Try uninstalling and reinstalling Parallax and see if that helps?

By any chance, did you install mods in the Steam copy of KSP?
