Interesting.. And weird.. Because I don't need csp to get the track loading.
The default CSP config when installing it can cause a massive fps drop for sure.
But you can just disable everything apart from the optimisations and actually gain performance
So install csp Version 0.1.76 and then click on my link to get the preset loaded or drop the preset file in the correct folder and then select the preset in csp.
For the preset selection, you need to be in the "General Patch Settings" of CSP.
It's the top entry of the "Extentions". Upper third on the left.
Then the preset drop-down menu is in the bottom bar of content manager.
You should then see all extentions apart from the general patch settings being gray.
