I've been messing around with the HLSL prescale X and Y settings and to my surprise, I discovered I can actually turn it up all to 14...yes FOURTEEN....before it boots into the game showing some strange black and white screen that's off to an angle. People in this thread were talking about hitting performance limitations at prescale x and y 6, so how in the world am I able to go all the way up to 14??? My CPU is not that great...an Intel 950. My GPU is an Nvidia Geforce 680 4GB. Certainly a fairly old card by today's standards. So what's going on here?
Is it because I have the MAME video pre-scale option set to 0? It's funny because if I turn that up to like 2 or 3, my screen becomes extremely blurry on the right side while sharp on the left. Is there ANY benefit to setting MAME's video prescale option to anything other than 0, if you've got your HLSL prescale X and Y set to 6 or above? Does the MAME Video prescale option alter or affect the way HLSL's prescale option works?
Please let me because I'm fairly puzzled at the moment.
