For some reason my D3D app is capped at either 60 FPS. I have params.PresentationInterval set to D3DPRESENT_INTERVAL_IMMEDIATE, and I don't have VSync enabled in my video card settings or anything either. And if I try to slow it down by adding a bunch of text or sprites to the scene it doesn't go down to 50 or 40 FPS, it jumps all the way to 30, then 15, then 7 or 8, which seems really strange because those are all (roughly) factors of 60. Any ideas what's going on? I'll post some of my code if necessary.

Well that definitely sounds like VSYNC is being enabled, one way or another. Do you get any different behavior in full-screen vs. windowed?

The only way I know of to disable VSync is to go into the nVidia contol panel and force it off, which I did, and I'm still getting the 60FPS cap. I noticed that I also get the cap when running other code from D3D tutorials; however I don't get it when running games or Irrlicht demos using D3D. Is there anything else I should be doing? Are there any specific parameters I should be setting or anything?

Yep, I did that, as I said in my first post.


Oh, apparently I didn't read your initial post... Damn MTV!

Anyway, to more things to check:
* Are you running fullscreen or windowed?
* Are you running XP or Vista?
