A: Yes. Modern GPU drivers are 500MB+. The G33/G31 driver is small because it lacks OpenGL 4.x, Vulkan, or shader model 5.0 support.

This is a mixed bag.

If you're not comfortable with manually searching for and installing drivers, you can use the tool. This tool scans your system, detects the chipset, and recommends the best driver for your system.

Boot into Safe Mode (tap F8 during startup), uninstall the driver in Device Manager, and try an older version of the driver package. Performance Tip: Add More RAM
