Oculus Rift Runtime, Graphic-Settings, Optimization (Windows)

The configuration of the Oculus Rift DK2 is a big topic. We made tests with different drivers, graphic-settings, tools, etc. Our test-application was Affected v1.55, which is by the way in my opinion one of the best games for the Oculus Rift DK2. Micha will tell you more about this game soon.

Test Device:
Acer Aspire V3-772G Notebook
Windows 8.1 64-bit
Intel Core i7-4702MQ 2.2 Ghz
NVIDIA GeForce GTX 760M
32GB DDR3 Memory

Oculus Rift Runtime
We tried 3 different versions of the Oculus Rift Runtime: 0.4.2-beta, 0.4.3-beta and 0.4.4-beta
To make it short: The best driver of our test was the Oculus Rift Runtime 0.4.2-beta:

Version	Test-result
0.4.4-beta	When I moved my head in the game, everything is getting double (most effected the text on the wall). Only 35 FPS with direct to rift and 60 FPS with extended mode.
0.4.3-beta	Same as above
0.4.2-beta	No issues like in 0.4.4-beta and 0.4.3-beta. Runs without lags und perfect graphics. Constant 75-76 FPS in direct to rift mode.

If you also want to display your FPS, you have to press 'Space' in the VR-Application (works in Affected and some other applications).

Graphic Settings
At first we used the NVIDIA Driver Version 347.52 which worked very good with Oculus Rift Runtime 0.4.2-beta. But sometimes there were some lags, which annoyed us a bit. In Affected v1.55 you can press 'M' to refresh the picture of the game only on the Oculus Rift, which reduces the lags.

But the best solution for this problem is, to install the NVIDIA Driver Version 344.75.
It also raised the frame rate to 77-80 FPS.


We also made some custom settings in the NVIDIA Control Panel:

Manage 3D Settings:

Preferred graphics processor: High-performance NVIDIA processor

Feature	Setting
Ambient Occlusion	Off
Anisotropic filtering	Application-controlled
Antialiasing - FXAA	Off
Antialiasing - Mode	Application-controlled
Antialiasing - Setting	Application-controller
Antialiasing - Transparency	Off
CUDA - GPUs	All
Maximum pre-rendered frames	1
Multi-display/mixed-GPU acceleration	Multiple display performance mode
Power management mode	Prefer maximum performance
Shader Cache	On
Texture filtering - Anisotropic sample optimization	Off
Texture filtering - Negative LOD bias	Allow
Texture filtering - Quality	Quality
Texture filtering - Trilinear optimization	Off
Threaded optimzation	Auto
Triple buffering	Off
Vertical sync	On
Virtual Reality pre-rendered frames	1

Set PhysX Configuration:
PhysX processor: GeForce GTX 760M


If you still have lags, maybe the next topic will help you a bit.

Optimization
Reset Oculus Rift view:
Sometimes there are lags if you didn't adjust the Oculus Rift view. Sit or stay in the position in which you want to play and press 'R' (works in the most applications) to reset the view.
This solved our biggest problems with lags.

Disable Aero:
To disable Aero had only a small effect to the lags. When we changed to NVIDIA Driver Version 344.75 the impact wasn't noticable any more but maybe it's the solution to your problem.
For disabling Aero you preferably use the Oculus Service Manager.
