Issue Details: Recent Graphics drivers seem to be incompatible with OpenGL v.1 & v.2, not sure about v.3. Running any openGL application will cause massive CPU load along idle GPU, in worst cases - crashes,errors,etc. However applications with OpenGL v.4, not sure about v.3 .. are running GPU based, fine and smooth. Old versions of OpenGL dont even trigger the Core/Memory Clocks, they stay default in x16 v.1.0. mode.
pictures of furmark openGL test:
note: newer versions of OpenGL works fine
gpu: 7850hd 2gb, saphire, not overclocked.
driver: 13.10 beta (9/5/2013). Tryed before 13.4 (5/29/2013), and previous versions
OS: Win7 Ultimate x64 SP1 by Ctrl Soft (NOW). Also tested WinXP x32 Game Edition 2010, WinXP x32 SP2 by ZverCD 2008. I stay with Win7 because i get the best performance overall
My Settings: Vsync,TrippleBuf,AA,AF,PostProcess - ALL OFF. The game itself has a configuration, that's configured by me for optimal performance.
Motherboard: Biostar A960A3+ ATX
small notice: mobo has pci-e x16 v.2.0, but the card is pci-e x16 v.3.0
PowerSupply: Xilence XP580 , 580w
Display Device: Dell P1130, 20" CRT, max refresh rate 160hz
Application & Games: Cryzis 2,3 , Risen2, Path of Exile,Witcher2 etc ..were running at High/Ultra without issues,very smooth. But OpenGL games like QuakeLive or Quake3Arena have horrible performance
CPU: AMD FX-4100 Quad Core , 3.60ghz. Not overclocked.
Motherboard Bios version: default,from instalation disc that came with MB
System Memory Type: 1x4gb DDR3, 1600mhz
Additional Hardware: sata II HDD 80 gb,onboard sound and lan, newest drivers.. Average person's hardware...
Additional Details: No viruses because installed a fresh Windows on a formatted hard drive. DPC Latency shows without any yellow/red spikes 100-150microseconds as it should in win7. BiOS is loaded at optimal settings(default)
