hello,
what is Gem framerate, your screen framerate, and do you use sync to vblank? all of this can increase latency of the screen side...
yes of course. obviously for a feedback image you won't get better than the lowest framerate. so here's some more information: - sync to vblank is turned off - Gem's framerate is 100fps - display is a Samsung SyncMaster DFP 1280x1024@60.02Hz
timing image attached a last time (cannot resist)
i changed the network settings to use jumbo frames: # ifconfig eth1 mtu 9000
the networking card i use is (i think): "Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Ctrl."
i haven't seen any problems with the images since. (though just before it was basically 2/3 white stripes)
cyrille, did you ever try jumbo frames?
