Oh, ****. Do these builds have shadows and deferred lighting? Turn those off if possible.
Yes, Nightly builds since mid-May have the new renderer, and shadows and deferred lighting are enabled by default. So anybody having terrible FPS or graphical problems you didn't have with 3.7.2 Final, turn off shadows and (if that doesn't fix your issues by itself) deferred lighting and if you still have problems, please post your fs2_open.log file. Instructions on how to do this can be found in this post.
I know only the first two WIH acts have received voice acting, but Tenebra (Act 3) is supposed to be in the release package right? I posted a link to the new download on another forum and someone said he/she couldn't find it.
Make sure they know that Act 3's campaign is called "Blue Planet - War in Heaven 2"; lot of confusion about that when Act 3 was first released as well.
So I disabled both and it kind of fixed the issue with the cockpits but it definitely fixed the issue for the framerate. The new issue I have is that the right side of the Erebus (the model I chose to test for the framerate) looks distorted (hard to describe; I'll post a screenshot soon). I have attached my debug log to this post, and I also posted the error I got below, though I don't know if it is related.
