just if thas a pending duty... if the monitor refreshes at 75 Hz then the grafics adapter has no need for producing more then 75 frames per second.
having images updated before the cathode ray has finished one image leads to showing two images in a single refresh cycle which looks bad. if you are rendering slower than 75 frames, you might show the same frame twice, but thats nearly not dramatical in image quality. there are means of ignoring the monitors refresh rate for e.g. benachmarking the board performance which is typically described as "sync to vsync: off". as written, it looks bad if you let it render like that. -Alex. > -----Original Message----- > From: Keith Whitwell [mailto:[EMAIL PROTECTED] > Sent: Saturday, October 18, 2003 18:23 > To: Eddy > Cc: [EMAIL PROTECTED]; Felix Kühling; dri-devel > Subject: [Dri-devel] Re: [Dri-users] Finally DRI is "On" but slow fps > > > Eddy wrote: > > Dear mailing list, > > I have been trying to get DRI working correctly but haven't > succeeded > > obviously.. > > Many configurations failed for me.
