The Turing RTX 2080 versus the Pascal GTX 1080 Ti Benchmarked with FCAT-VR

Less than two months ago, NVIDIA released its new Turing RTX 2080 which is a little faster than the Pascal GTX 1080 Ti in gaming performance. We naturally want to see how they each compare in Virtual Reality (VR), so we are following up with a five-game performance comparison measuring frametimes and unconstrained performance using FCAT VR.

BTR has a 25 VR game benchmark suite, but this editor has been unable to enter VR due to a long illness without getting VR sick since May, and we are just now easing back into it. Since we posted our original review, we have benchmarked many more VR games in our follow-up reviews over the past two years. We have even compared FCAT VR with our own video benchmarks using a camera to capture images directly from a HMD lens. For BTR’s VR testing methodology, please refer to this evaluation.

We will benchmark five Oculus Rift VR games with the GTX 1080 Ti Founders Edition versus the RTX 2080 Founders Edition using Intel’s Core i7-8700K at 4.7 GHz, an EVGA Z370 FTW motherboard and 16 GB of Kingston HyperX DDR4 at 3333 MHz on Windows 10 64-bit Home Edition. Here are the five VR games that we are benchmarking:

Until FCAT VR was released there was no universally acknowledged way to accurately benchmark the Oculus Rift. To compound the difficulties of benchmarking the Rift, there are additional complexities because of the way it uses a type of frame reprojection called asynchronous space warp (ASW) to keep framerates steady at either 90 FPS or at 45 FPS. It is important to be aware of VR performance since poorly delivered frames will actually make a VR experience quite unpleasant and the user can even become VR sick.

It is very important to understand how NVIDIA’s VRWorks functions to deliver a premium VR experience, and it is also important to understand how we can accurately benchmark VR as explained here. And before we benchmark our five VR games, let’s take a look at our Test Configuration on the next page.
