This is the April 18th release! http://www.driverheaven.net/vista- [...] ost1140620
Nice.
Is this really any better for a 8600GT over the latest official released driver?
Ive seen those, people that tried em either had issues with them or they helped, up to you
What kind of performance increase? Is it worth the risk?
Theres no serious risk I think, you can always revert back. Just make a Windows Restore point!!! I didn't have time to install them yet. I was at work, but I'll do it tonight and have some benchmarks up 2morrow
