Framerate problems with shaders on pretty powerful specs

[vdriftfan]

I forced it off from the nvidia control panel. It didn't work. I have the same issues. By the way, XS(S2000) tail lights aren't transparent. I'm not having the same issue on all cars though. 350Z doesn't have visible stop lights yet rear gear lights work. All textures and files are present in the cars folder so it isn't caused by incomplete downloads.

Edit: Sorry I forgot to write that problem persists regardless of resolution. 640x480 or 1280x720 same framerate. It's extremely strange, for me at least, to see this behaviour. Usually lowering the resolution made the FPS sky rocket. Also here's the pic I uploaded.

Sorry for multiple uploads of the same image. Can someone please delete the 2 most recent ones. Even if i got the error, the pic was actually uploaded.
