[H]ard|OCP weren't too happy with SLI when it was reborn, particularly in the area of games supporting it. I've had no complaints myself, but there we go. Revisiting the issue, they still have concerns.
We are still very concerned with the frequency of driver releases and bug fixes, however. As you can see in our gameplay testing, this driver has quite a few problems. Right now, there is a temperature issue bug, and a bug with Coolbits not allowing overclocking in SLI. Then there are gameplay bugs that affect performance and gameplay, such as not being able to run in SLI in The Chronicles of Riddick and having stuttering in EverQuest II, which is hampering the performance benefit of SLI in that game. It worries us that it has been four months since the last official driver release.
