I recently bought the HP Envy 15-3040nr laptop with the following specs:
OS Version: Microsoft Windows 7 Home Premium, Service Pack 1, 64 bit
Processor: Intel® Core™ i7-2670QM CPU @ 2.20GHz, Intel64 Family 6 Model 42 Stepping 7
Processor Count: 8
RAM: 8139 Mb
Graphics Card: AMD Radeon 7690M, 1024 Mb, Switchable with Intel® HD Graphics Family.
Motherboard: Hewlett-Packard, 1688
After a couple of days of use, I realized that the dynamic graphics mode was a failure and the High Performance card (the 7690M) wasn't being used. I changed the graphics mode to fixed from the bios and I had the ability to change between High and Low performance graphics cards. Now games would play with much better performance (Minecraft for instance reached 100+ FPS and I had to use the Vsync option to avoid the AMD card crashing).
Later, I tried out an After Effects plugin called Element 3D (by VideoCopilot). The plugin relies heavily on OpenGL. Whenever I launched the plugin, After Effects crashed. I later read that I needed to use version 12.7 of the catalyst. I downloaded it and the plugin worked wonderfully. However, the AMD card's performance went very low (Minecraft had only 20 - 35 FPS, and other games lagged horribly). I posted on other forums and I was told to revert back to the original catalyst and drivers that came bundled with my laptop. I downloaded the following driver from the HP Website: Link I first uninstalled the current catalyst and driver using the installer I downloaded from the HP website and I used the following guide to guide myself in uninstalling. I restarted my laptop and the resolution was all messed up. I then installed the original drivers and catalyst and everything went back to normal. However the performance didn't change a bit. Now the Intel graphics card performed better than the AMD one. My fear is that it could be a problem in the card itself that was caused by the 12.7 catalyst and drivers. However there might be a different way to uninstall the the drivers that I don't know about. How can I fix this problem?
Thanks in advance.
