So for me right now the game is really laggy when vsync is on, and somewhat laggy when rolling up into a ball if compatibility mode is turned on. Bloom seems to be fine, and I never use motion blur regardless of the game (motion sickness!)
While flying around I got several instances of a message in the top left corner saying "trail would have crashed the game". Also, if you press "F" at any point, the screen does a fadeout and fadein as if it still thinks you're on the title screen.
Thanks for giving it a go again!
I've been experiencing a little lag when using vsync as well, it's good to know that it's not just me. Strange that you're getting the trail warning though, it should be turned off unless it's in developer mode, I'll look into it. Compatibility mode was added a while back when I first added lighting, and I can't quite remember what it does - doesn't matter much though, cos it looks like it's broken! Current plan is to both fix it, and make it automatically switch (if possible).
