TL: DR what I have learned.
- My local benchmark table cannot be copied over to the forum in one click :,-(
- Flatscreen resolution does not seem to affect performance (when in VR)
- SteamVR resolution and HMD quality in-game have comparatively the same effect on performance
- Other SteamVR options did not influence performance but can affect comfort (motion smoothing, auto throttle)
- Default VR graphic profiles in ED are not necessarily “optimal” depending on your headset. They have been used to get the same reference point for others
- There is a bigger decrease in performance between VR medium and high
- Station interiors are the most demanding of the scenarios tested
Introduction
I wanted to see if my VR experience is similar to the average.With many different hardware combinations (computer and VR headset) as well as a lack of real VR benchmark, I went on to establish some protocol to get repeatable measurements.
Having a SteamVR native headset already put me on a specific use case but I think comparing with other compositers (hopefully that is the right word) can still be useful.
My configuration (using a mix of system info and HWiNFO)
- Intel i5 12600K @3.7 Ghz
- 32 GB RAM DDR4 3200 16CL
- Geforce RTX 4070 (GV-N4070WF3OC-12GD)
- XPG GAMMIX S70 BLADE NVMe 1TB
- Bigscreen Beyond VR headset, 3560x3560 100% SteamVR resolution 75 Hz refresh rate
Test protocol
- Game version 4.1.0.2 (Odyssey)
- Use the SteamVR in-headset performance indicator counted in milliseconds (ms), lower is better
- Look as straight as possible, using cockpit elements as reference
- Use the various training scenarios to help with consistence
- Get the performance reading 5-10 seconds after loading has finished
- Surface Operation (on-foot tutorial) has two values, flatscreen and VR using the default external camera facing your Commander
- Advanced SRV/SLF does NOT benchmark SRV or SLF performance, just the initial situation
- SRV pratice benchmark SRV performance
- Verify repeatability by re-running some of the tests and getting close results
- In-game time when the tests were run has been indicated. I am not sure how much this can impact the performance in the various systems used in tutorials
- SteamVR specific
- Motion smoothing off
- Throttling behavior fixed 90 FPS, 0 ms additional prediction
Conclusion
- A Geforce RTX 4070 is not enough to run the Beyond at its native resolution but an “acceptable” experience can be found by lowering resolution and graphic settings
- The benchmark scenarios, while diverse, lack specific game scenarios (neutron star, repeatable multi-ship flight/combat, etc)
- Hopefully people can contribute with their own benchmarks and we can compare results
- It’s definitely not a perfect protocol, I am happy to take constructive feedback, o7
