That's very interesting - I don't notice any strong jitter on the PCs I use.
ok, that's good to know and a good start!
I will recheck my systems, tomorrow.
If you have a PC with multiple graphics chips, can you make sure you're running the demo with the dedicated one?
Yes, I can make sure of that. I tried different systems including systems with only one graphics card and I had also an eye on the graphics card which was used (in case of multiple graphics chips).
Also, make sure to build in release mode, not in debug mode. Debug will be much slower.
Yes, I took this into account. I tested also the release build on every system.
I will try to add a framerate display towards the end of this week. Then we can compare framerates and rule that out as an issue.
I added a framerate counter. With the system I'm currently using, I achieve a framerate of ~400fps (GeForce GTX 560 Ti) when running in release build.
Another thing you could try is is to animate one of the boxes - then see if just the head movement is slow or if the box update jitters as well, when you don't move the head.
Good idea, I just tried that and rotating the boxes looks fine... no jitter effect. Yesterday, I added some code to automatically move the camera and this looked also fine (in contrast to me... I felt a bit cybersick afterwards
What system are you running on? What OS, which hardware setups?
I tried only Windows 7.
Unfortunately, I did not have enough time today to test the different systems again. I will do some rechecks tomorrow and provide you with the detailed results (fps, gpu type,....). But thank you very much for your input!
