ribbell I've modified RT's GPU enumeration routine to allow it to enumerate physical and logical display devices in multiple passes, so I hope that 4870 X2 issues are solved now. Also, new GPU enumerator should give big advantage to RT: now it must be able to "see" unattached display devices too (i.e. physical display adapters not attached to any logical Windows display device and invisible to OS). In other words, now low-level diagnostics, monitoring and fan control will be also available when Windows is loaded in safe mode with no display drivers installed and also low-level settings should be available for slave GPUs in SLI/CF configurations too. So if everything is working as supposed then I think that we can say "hello" to official CF fan control support in RT. Test build is on the way.
