Serious Sam VR mGPU NVIDIA GTX Pascal Follow Up

Serious Sam VR was the first commercial enthusiast gaming title to include multi-GPU support with AMD's RX 480 GPU. Now the folks at Croteam have added mGPU support for NVIDIA cards as well. We take a look at how well NVIDIA's VRSLI technology fares in this VR shooter title.

Serious Sam VR and mGPU

If you have not checked out Serious Sam VR: The Last Hope, it is an Early Release title on Steam that uses the Vive VR system with motion controllers. We originally reviewed SSVR GPU performance last month. Immediately after that, we followed up with a quick article showing SSVR mGPU support using AMD's RX 480 video card and it showed to have excellent scaling. Last week, Croteam and DevolverDigital updated SSVR with NVIDIA VR SLI support.

Build 279777 for Serious Sam: The Last Hope is released.

Here are the changes:

- Added support for nVidia VR SLI.

- Minor gameplay fixes and tweaks.

- Various performance optimizations.

Of course we wanted to see NVIDIA mGPU in action and that is what we are looking at here today. We are going to be jumping right into performance results, so if you are wondering more about how we collect our real world VR gaming data, you can read all about it on this page. Of course we did use the latest NVIDIA WHQL Driver v376.09.

Serious Sam VR TITAN X Pascal Performance

I thought we would lead off with the TITAN X Pascal, sadly I do not have two TITAN X Pascal cards to use, but we will be laying down single card performance data to give us a baseline for GTX 1080 and GTX 1070 results.

For our previous SSVR results we have used High-High-High "Performance" option settings. Above we have those results in addition to Ultra-Ultra-Ultra IQ settings as well. We do leave Level Caching off for both as it has no impact on our results.

Our H-H-H settings return an average GPU Render Time of 4.792ms, which is a bit faster than our previous results due to game and driver optimizations over the last month. Moving to U-U-U settings we see our average GPU Render Time move up to 6.493ms. That said, the TITAN X Pascal is fast enough to deliver the same VR experience with the highest preset IQ options.

Let's move on and see what our mGPU cards do.
