Forza Horizon 4 PC Performance Review

Low-end GPU testing - R9 380 VS GTX 960 - Is 2GB of VRAM enough?

AMD's Radeon R9 380 and Nvidia's GTX 960 have been part of our graphics card test suite since 2015, allowing us to judge the performance of games on mid-tier hardware with limited amounts of VRAM. Over time we have gradually seen the gaming world chip away as these two graphics cards, with VRAM requirements increasing as developers learned to utilise the large frame buffers offered by the PS4 and Xbox One (when compared to prior consoles). 

In Forza Horizon 4, game performance takes a nosedive when using AMD's R9 380 and Nvidia's GTX 960, offering less than 35% of the performance of our RX 580 and GTX 1060 graphics cards. In most older games, these graphics cards typically provided around 60% of the performance of the RX 580 and GTX 1060. In Forza Horizon 4, the RX 580 and GTX 1060 offer better performance at 4K than the R9 380 and GTX 960 can deliver at 1080p. Time has not been kind to these two graphics cards. 

Our GTX 960 graphics cards can maintain a framerate of over 30FPS at High settings, while the RX 380 needs to use Forza Horizon 4's medium graphical preset to accomplish the same performance feat. These performance levels can come down to many factors, from VRAM capacity to graphics architecture. We have already seen how Forza Horizon 4 benefits from using AMD's Vega architecture and Nvidia's Turing architecture, perhaps the opposite holds true when moving backwards from Polaris to GCN and from Pascal to Maxwell.

Considering 1080p is my best (poor eye sight) I'm well impressed at how well it runs on Ultra, and I do like the Forza Horizon gamesQuote

Vega 64 only 1.6FPS behind a 1080 Ti at 1440P, Impressive.Quote

Yeah, Forza is a great showing on Radeon's Vega graphics cards. It's well strange that the RX 580 and GTX 1060 are level pegging, but the Vega 64 demolishes the GTX 1080.

Anyway guys, all feedback is appreciated here. Feel welcome to post criticism, especially for the video, as it is our first time doing that.Quote

Wow, that is the first time I've ever seen Vega match a 1080Ti in gaming. Even games that favour Vega specifically like Far Cry 5 and Wolfenstein II don't show Vega being on par with the 1080Ti; it was always still slightly behind, at least from what I've seen and remember. Very impressive.

Also, OC3D's video game analysis articles are one of the only places I know of that shows performance scaling with different in-game settings. There's nothing worse than seeing a graph for a game where a GTX 1080 or Vega 64 can't hit 60 FPS at 1440p in a new game at max settings but easily hits 80 FPS with just a couple of superfluous settings turned down or off. So thanks very much for the extra work.

On a similar note, what I think could be the best way to test a game is to have target FPS points. So for instance you'd have a GTX 1050/RX 460, GTX 1060/RX 580 and GTX 1080/Vega 64 comparison, and you'd show what the graphics settings would need to be in order to hit 60, 90 or 120 FPS, maybe with screenshot comparisons as you guys already do. So if I had a GTX 1060, I'd know that in AC Odyssey I'd have to use FXAA and High shadows in order to hit 60 FPS at 1080p, or I'd have to turn off a couple of other things to hit 90 FPS. The same thing for the other cards. It would take a lot of work and may not be possible for most, but it would be the best way to do things in my opinion. I always appreciated Nvidia's breakdown of AAA games and their graphics settings. It basically meant that if I had for example a GTX 970 and still wanted to hit 60 FPS at 1080p, I'd know that either I'd need to upgrade my graphics card, or how far I'd have to reduce the in-game settings to hit that point, or whether that was something I was willing to do.

Again, excellent work, Mark and all those involved.Quote

Look at the vega 56 compared to 1080 too!Quote
