Bug Report Lots of lagged frames?

[Piximan]

Playing in game (tribes ascend) and having some noticeable jitteryness which I do not get under xsplit (free version). I tried messing with vsync - that did not help. In-game FPS stays about the same when streaming (~70-90 fps). I checked the log and there is a huge number of lagged frames (which i don't see in other people's logs). Not using dxtory or anything - just capturing the one monitor screen I have and playing windowed/borderless. What causes the lagged frames?

Thanks in advance for all the help - I'd love to use this program if I can get rid of the jitteryness in game.

do you have aero off?

 

[Piximan]

Turning aero off on startup reduced the number of lagged frames, however i'm still getting a bit of choppy feeling. i tried messing with the buffer sizes as an earlier poster had mentioned. Playing with the values seems to have quite an effect of jitteryness for the game - and i see intermittent dropping of b-frames. Would more playing around with this setting help you think?

try out window capture instead - can't see your desktop, but it's usually much better on the game like that, and you can leave aero on (in fact it's better to leave aero on with window capture)

aero -must- be off when using monitor capture though, otherwise it just can't capture very fast.
