RDR2 VR Mod Highly Unlikely Due to Lacking Horsepower, Says Modder
RDR2 VR may remain a dream on PC, even with the dedicated modding community of Rockstar fans. That's what Luke Ross, creator of the Grand Theft Auto V VR R.E.A.L. mod, wrote in a Reddit post a few days ago.
According to him, an RDR2 VR mod won't be possible any time soon simply due to the lack of the necessary horsepower on PC, at least for the time being.
[...] I just finished a few benchmarking sessions with RDR2, and the news is not good. With Balanced (default) settings, at the resolution and FOV needed for "real" VR, Red Dead Redemption 2 struggles to reach 40 fps on a system with i9-9900K, 32 GB dual channel, GTX 1080 Ti, and of course SSD.
To be clear, that's less than 40 total frames per second, or less than 20 per eye, even with alternate eye rendering.
With Performance settings, i.e, basically everything on Low, it runs at around 60-70 total fps (30-35 per eye, still not enough), and it looks like... well, you can imagine.
Please don't take this to mean that the game is not "optimized" as kids on the forums love to say. At 1080p, it pushes more than 80 fps (in other terms more than needed) while looking gorgeous. But there is no way that during 2020 a new GPU will come out that will be able to render RDR2 at the combination of quality, resolution, FOV and frame rate that is needed for proper VR. With SLI completely dead and no longer supported by either games or VR runtimes, there is not even the possibility to throw heaps of money at the problem.
Additionally, my GTA V mod was built around 3Dmigoto, which is limited to DX11, whereas RDR2 surprisingly came out supporting only DX12 and Vulkan. Unless 3Dmigoto is extended to DX12 (extremely unlikely), or RDR2 is backported to DX11 (yeah, sure), the mod would need to be rewritten from scratch, together with a new hooking library.
TL;DR: Don't hold your breath for a proper RDR2 VR mod that displays it in its full glory, the software and most importantly the hardware is just not there.
It is true that Red Dead Redemption 2, while looking stunning, is also very demanding on any PC system as our Keith put it. VR, due to its very nature, would basically require double the performance.
That said, we'll definitely let you know if an RDR2 VR mod is indeed released at some point in the future.
