Hello!
I own a Dell Optiplex 3020, my old GT730 died recently so I had to switch to the integrated HD4600.
Using the latest drivers provided by Intel, or even the drivers from Windows Update causes rendering issues to DX9 games, haven't seen any issues on DX10 or above games.
Using the drivers provided by Dell's website stops this issue from happening completely, although the drivers are way outdated, being last updated in 2015. Doing some benchmarks I found out that the newer games are negatively affected in performance when using the old drivers provided by Dell. The processor is i5 4590, everything is stock except for an added 4GB stick, I'm using a 1080p monitor running on HDMI, Motherboard only has DisplayPort and VGA, so I'm using DP to HDMI adapter.
My apologies if I'm on the wrong forum. Any help will be appreciated.
