To help with stability we have moved back to the stock egl drivers for CM7. The problem with the updated drivers that Whyzor used, was no one knows where they exactly came from

I spent about a month trying to figure out what ROM those drivers came from and I for one could not find it. The problem is when you update the system/lib/egl there is also files that need to go into system/lib/ and system/lib/hw. If you notice on Whyzor's commit there is no system/lib/hw file updates at all. So the drivers we where using are partially there.
If you are looking for faster video drivers I would recommend using the current CM9 as it's averaging 25.8 FPS. This is based on using Nenamaerk2, the average came from 5 tests with completely opening and closing the Nenamaerk2 app.
The new egl drivers I put into the CM9 ROM came directly from Qualcomm's developer site and are written specifically for Ice Cream Sandwich. Since Qualcomm has not released a true download for Gingerbread I for one believe the stock drivers are best way forward. They may not be as fast but I am sure you are seeing the difference in overall stability and smoothness of the ROM. If some one can actually find the whole set of drivers we can try to upgrade them and see if it helps.
