Hey, I'm running multiple monitors for debugging, and there's something that's more of an annoyance than a problem, but I wanted to see if it's related to the way Windows deals with multiple monitors, if anyone knows the answer. Basically, Im running a Savage4 chipset with 8 megs (AGP) (it's a pretty good card) on my primary display. On my second one, Im running an I/O Magic card with a Permedia chipset (I think) (PCI), that's a pretty cheap card My game runs at 640x480. The refresh rate of monitor #1 is 85 hz at this res, and monitor 2 is 60 hz. If I don't call my level drawing code, the rate on monitor 1 is at 85 and monitor 2 is at 60. If I do call my level drawing code, monitor 1 is still at 85, monitor 2 drops down to 30. I can't see how my drawing code could be that slow, and I also can't see why it would drop the framerate 30 fps on one monitor, and none on the other... So I was thinking it might have something to do with how windows handles multiple monitors? I'm running this on Win98. The second monitor is a very old monitor (but I can't see why that would have anything to do with it). Do I need to give more info? Anyway, if anybody knows anything, any help would be greatly appreciated! Edited by - IdEstVita on 7/31/00 3:06:35 AM

there's a tutorial on xgames3d.com on this subject if that helps any.

Beat you on that, I''m using a G400 MAX DH (32MB)

On my main 17" monitor I get the full refresh rate (at the res I run it''s about 60) but on my second monitor (a TV) I get ~1 fps.

if you enum the devices correctly (and look at the multi monitor SDK example for DirectX) you can get a good display / FPS

I ran the multimonitor SDK Sample and got a good steady fps on both ''monitors''.

Thanks so much!

And Julio, to my knowledge the xgames multimonitor thing only deals with monochrome monitors, which is not the same as having 2 VGA monitors installed.
