Why 4K is difficult to run
Not many PCs can run games in 4K, let alone 4K 60fps. Running games at this resolution is difficult because it’s like running a game on four 1080p monitors. Not just “like”, that’s exactly what’s happening. When it comes to the mainstream 4K is usually a 3840×2160 resolution. If you do some quick math, we can see that 4K is the same number of pixels as four 1080p monitors.
Which graphics card you need for RDR2 in 4K
Now that we know why 4K is so hard to run, let’s get into what you need to be able to run RDR2 in 4K 60fps. Graphics cards have become seriously powerful in recent times. You no longer need a crazy $2000 PC to run games in 4K. Of course, it’s still not cheap, but it’s getting cheaper with every generation.
The NVIDIA GeForce GTX 1060 is a few years old at this point. It was released in 2016, but it’s still a very capable card. Depending on the game, you can expect 30-45fps with medium to very-high settings. Not bad at all!
RTX 2070 Super
We’ll have to step things in order to play RDR2 at 4K 60fps with the best visuals. A high-end card like the RTX 2070 Super is where you want to start looking. The RTX 2070 Super will average around 60-70fps on high to ultra settings. With this much horsepower, you won’t have to worry if you can run RDR2 or not.
On the Red team you’ll want to start with the Radeon RX 570 for 4K gaming. With medium settings, you get a playable 30fps on some harder games to run. On easier games like Overwatch, you’ll achieve higher frames. Kicking it up to the max that AMD offers, the RX 5700XT should be your choice for no compromises. This card has very comparable numbers to the RTX 2070 Super.
Depending on how well RDR2 is optimized you might have an easier or harder time running it. Once it’s released, we’ll update you on how well it performs.
