Thanks! Can i ask, how does Soft15Khz get around the dot clock restriction on the ATI ~700-3000 cards? Do NVidia cards have this restriction as well? And if so, does Soft15kHz double the horizontal resolution to cope?


SailorSat:
It does not include any "workaround" for low pixel clock limitations.

I am trying to get Soft-15KHz to work on my computer to arcade, but so far It hasn't worked. :banghead:

I've installed Soft-15KHz to my Windows 7 system, I have the most up to date drivers for my GeForce 6200, and I also set my resolution to 640x480 with QRes. 

I turned off my CPU, plugged in the vga to my JPAC, to my Jamma Harness, and I get video on my CRT.  The problem is that it's a screen and a half.

I don't get any lights lit up on my JPAC, so I assume it's not sending the 15KHz signal correctly.

Is this a known issue?  Any help would be lovely.

When I developed the NVidia_NT6 implementation (Vista/Seven) in 2010, I used driver version 257.xx and a GeForce 7600... Most likely the driver structure has changed in the last 5 years .)

What do you recommend I use them to have decent power without having to change my power supply but can still run games and hyperspin?
