I have a strange resolution problem. We have a pretty simple game with fairly lame graphics. We are running it on a projector whose native resolution is 1280x720. I use to be able to run my game at the native projector resolution, and it looked fine, but then something changed, and I have no idea what. Now when I run my game at this resolution, it tends to look choppy while turning, and generally seems to be running at a lower frame rate, which indeed it is. So at the resolution 1280x720, my frame rate drops to around 50fps, but if I set the resolution to 1024x768, frame rate jumps up to 120fps, and everything looks fine, although at a lower resolution, obviously. It was not a video driver update, which was my first thought. I have no idea what it was, but I have actually completely re-installed the operating system, drivers and software at this point (even playing around with not letting it do updates), and none of that has made any difference. The computer is running Windows 8, and I have tried both a recent development version of Panda3d, and the last stable version. This actually happened on two different systems running mostly the same hardware/software. Even weirder, if I run the Carousel tutorial, it runs at 120fps at both resolutions. What about my crappy graphics is causing this, or is it my code, or something else? And why would it change when my code and models did not? Any ideas? Am I just stuck at the lower resolution? I’m so completely mystified.
