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
Running a Radeon HD 7970 video card with MSI Z77A-g43 motherboard, which has a PCIe 3.0 slot and I have the exact same problem. That's not the problem.
