I went to the Source you quote in your post and not even there seems to be much interest, 17 posts total. Go figure. There is actually someone there saying that while running Afterburner you don't have FPS on-screen, which I figured out how to solve
, which basically involves not running Afterburner at all but launching RTSS (Rivatuner OSD Statistics Server) on its own and supplying the HWiNFO values directly - including the GPU values that Afterburner normally supplies to RTSS. You really don't need Afterburner unless you are overclocking the GPU. If you are and you need to use Afterburner you'll have to use FRAPS to get FPS on-screen.
