Thanks to Bekas, and Ravenger re: the high performance timers.
I was thinking heavily about when I should broach that topic and, got lucky that it was brought up. I am going thru the tutorials, and noticed a problem with jitter.
In Tutorial2 (Mogre) there was a subtle yet distinct pattern of jerky motion / jitter that occurs when I use the left or right key to move the camera. This is much less noticeable when moving forward or back, yet still present.
I know its not my video card or my computer because they are reasonably good (sig below).
I have encountered this issue before, and it was related to excessive calls to render to the video card. I used FRAPS and its showing >600 FPS.
Previously I used a delta timing system, and only called the video card to render 120FPS. But that was using a different engine.
Since I am no expert in this area, I was wondering if you have any suggestion to reduce the # of calls to render? And where would I find the code that actually makes use of these calls so it can be edited?
Or perhaps, I am barking down the wrong tree?
Thanks for assistance,
MACK
PS, (I also had this jitter when using an inacurate timer, that for whatever reason could not measure anything less than <= 16ms.
