Hey i bought a sapphire 5770 and I've yet been able to find a way to get it running at 100hz on my iiyama 452pro at 1024. It won't go past 85hz on any res.
I had a sapphire 3870 which did manage 100hz at 1024 and 120hz at 800x600 using ati refresh fix 0.9.9.7
Also had a few nvidia cards which do up to 150hz on this monitor without any 3rd party programs.
I've tried reforce, refresh lock, basically every single program made for forcing refresh rates. Non of these seem to do anything EVEN with my old 3870. The only one that did was the "ati refresh fix" and thats just isn't functioning correctly with these new cards/drivers.
If anyone could shed some light on this it would be helpful. As the card is useless to me if i can't get it to at least 120hz @ 800.
