I updated my graphics drivers (Radeon 530) 2 weeks ago, hoping that it would increase performance on my laptop (Lenovo 81AX). But the games started crashing and some games started freezing, and I got a D3D9 device not found error on some Valve games. I tried doing a clean boot and using the AMD Cleanup Utility, but it just fixed a few of my problems. Everything was fine on the old driver. (This old driver shows as the latest on the laptop manufacturer's site.) The new driver is Adrenalin 22.6.1.
