I have a Viewsonic VX912 connected to an Asus AX800XT graphics card, via a DVI (digital) input. I wish to know, how would I enable vsync on this monitor? How would I find out if it is already enabled? Would it be enabled through the settings accessed through the front of the monitor, or through the graphic drivers, ie ATI CCC? Can it be enabled using either an analogue or digital connection or both? In what situation would "one" want to have vsync "enabled"? ie would it be beneficial to have it enabled for playing games such as COD2? This game, COD2, plays very well with the way I have everything set up at the moment, no "tearing" (I believe it is called), very high level of detail, no ghosting etc. In the ATI CCC, under the 3D settings, API Specific, OpenGL setting, I have Tripple buffering UNticked. In setting up the ATI CCC (using version Catalyst 5.13) I followed the ATI Catalyst guide found here: http://www.tweakguides.com/ATICAT_1.html Which I have found very helpful. Many thanks for your suggestions and comments!
