The final drivers are ready from both camps and Forza Horizon 4 is out! Well, if you were anxious enough to drop the dough on the Ultimate Edition. Everyone else will have to wait until October 2nd to burn rubber across the British countryside. But, that doesn’t mean we can’t give you a taste of what to expect performance wise from various graphics cards in this title.  We took a look at them demo already for those who are thinking they’re experiencing déjà vu so we aren’t going to spend a ton of time rambling on about the game.

Testing the game was a pretty straight forward process thanks to a built in benchmark that is very representative of normal in game performance.  The big catch is this game has a ton of options and quite a few variables so we had to make sure to disable those with each restart and hardware change ultimately settling with the non variable ‘Ultra’ preset. There are settings that will allow you to take things to the extreme, well that’s what they call it anyway, but we’re sticking to a solid preset for today. Testing took place at 1080p, 1440p, and 4k taking the average of 3 runs to account for margin of error, which there was very little between runs. The fact that it is both a UWP title and DX12 means that old world methods of extracting performance beyond what the benchmark spits out at the end.  We incorporated a combination of OCAT and an in house spreadsheet that extracts the Average Framerate as well as the 1% and .1% lows to better represent what the experience is in game. Below we’ve listed the hardware we tested with and the drivers used.
