AMD 7870 ddr5
After some googling i found a solution, you have to extract the atioglxx.dll from what ever driver version worked best for ET for me its 9.11 and place that dll along side ET.exe.
There appears to be a issue with all AMD cards that use drivers past 9.11 on any game older than opengl2.2
