EternalStealth, here is the problem. You have a graphics card built by AMD that is utilizing the PCIe 3.0 architecture. You have a motherboard that does not have a PCIe 3.0 slot. Instead you are using a PCIe 2.0 or 2.1 slot. Are you with me so far?
The AMD drivers, are causing issues with backward compatibility. Riot is a video game manufacture that creates a game that SHOULD be playable on a computer that meets the minimum system requirements.
You are trying to use logic to place blame on Riot with
League before patch = perfectly fine
League after patch = getting this issue
This is a logic fallacy. Correlation is not causation my friend. it is people like you who exhibit persistent obstinence in laying the blame on Riot instead of accepting that the video card drivers that you are using are the root cause.
Before update to beta drivers = graphical glitches
After updating to beta drivers = no graphical glitches.
I have responded to you before with your 3 options if you do not want to use beta drivers. Buy a new motherboard that has a PCIe 3.0 slot, get a graphics card that uses the PCIe 2.0/2.1 architecture, or stop playing LOL. You continue to complain instead of fix the problem that lies INSIDE YOUR COMPUTER
By your own statement, LoL should be playable on a computer that meets the minimum system requirements. This includes working with official driver releases. They can be forgiven for having issues with beta releases, but this is an issue with an official driver release. Additionally, it worked fine prior to the patch. Maybe there is something wrong in the official driver release, but if that is the case, then they could revert the calls to how it worked previously.
That said, there is a brand new official driver release dated 1/17/2013 version 13.1 that I'm going to try. Hopefully it'll work. For those that are interested: http://support.amd.com/us/gpudownloa...w_vista64.aspx
EDIT: I installed the new drivers and played a game. No flickering so far. These are OFFICIAL (and newer than the 12.11 beta) drivers, for those that are worried about beta drivers. To be completely safe, download the new drivers, extract and run the installer; select uninstall. Restart your computer when prompted or when uninstall completes. Run the new driver setup again (if you don't remember where it extracted the files to, just run the file you downloaded). Drivers will install and you'll be golden.
