Do you know what driver version you're running now?
I don't know what these new 78.01's will do...
I haven't bothered installing them....
But with a 6600GT PCI-E card.....
The 77.77 and the 77.72, worked fine with FF7PC and the TNTpatch.
Nv4dislp.dll sound like a Nvidia driver fault. It's very possible that your card doesn't play well with Nvidia's reference drivers. You may have to use the drivers that your video card manufacture has on their driver updates. And that being the case.... You're basicly on your own....they use their own driver version numbers....it's near imposible to refer a certain driver version, unless, someone has already did the homework for you. (in other words....if someone has already went thru the headach of figuring out what manufacture driver is the best one.)
Eh...doesn't really matter I guess...... Just make sure that the 8bit pallet says fail in the ff7config test, and you can use the TNTpatch with no worries. If it says Pass.....you need to find a way to disable it. Rivatuner is the only program that I know of that will disable it if it's enabled. 77.77 and 77.72 have the 8 bit pallet off, by default. I think even a few driver version under those have it off, as well. That's why it's easier to just recommend those drivers #'s.
