Simulation titles can provide some of the most breathtaking - and demanding experiences you can get in VR. To get them running smoothly on your hardware, there's a variety of tweaks that can be made on the SteamVR, application, and utility level for best results.

If you have a Beyond 2e, you can access powerful features like Dynamic Foveated Rendering (DFR) to improve your performance in supported titles. Many of the most popular sim options including DCS World, iRacing, and MSFS 2024 support this feature.

By rendering the focused area at full resolution while scaling down the periphery, you can reduce load on your GPU dramatically, leading to considerable performance gains in most situations.

When using DFR, ensure that...

• The eyetracking window is left open and running, and DFR is enabled

• You have the Quadviews OpenXR layer installed and running, for the titles that need it

• The "BeyondEyetracking" addon is enabled under SteamVR>Startup>Manage add-ons

DFR Implementation Status: Available via Quadviews OpenXR layer

CPU DFR performance impact: Moderate

To enable DFR: Enable "Use Quad View" and "Eye tracking" in DCS settings

DFR Implementation Status: Native through NVIDIA VRWorks (SPS). NVIDIA GPUs only.

CPU DFR performance impact: Low

To enable DFR:

Useful Resources:

• The Virtual Reality section of the iRacing forum

DFR Implementation Status: Native through Multi-View Rendering. Works on NVIDIA and AMD GPUs

CPU DFR performance impact: Moderate

Note: MSFS 2024 is a very CPU intensive title. If your CPU is bottlenecking performance, DFR will increase that load.

To Enable DFR: Enable "Foveated Rendering" in VR settings. Adjust "Foveated Rendering Scale" as desired (lower will increase performance, but decrease the size of the central focus area)
