0.3.2 SDK Benchmarks and Quality
My 1st impression of 0.3.2 was not very good. I had not run the configuration utility and just tried to drop the new OVR controller in place in my project. The result was a slower framerate and much p...
Yeah I don't think using an integer multiple matters here because this is the pre-distorted render texture size factor. The distortion twists everything around on this larger rendered texture and outputs into the final screen buffer of smaller size. So you can probably have a slider that tunes the setting (although I'm not sure you can adjust this at runtime).
BTW - the render texture size of the cameras is set by the SDK and appears to be based on the eye relief/FOV as well. It is not influenced by the screen size you select with the player (I confirmed by using some log messages). I assume this render texture size will vary based on the device being used (DK1, DK2, etc.).
I found with eye relief at notch 1 (7mm for me - thanks brantlew for that info!) the render texture size is 2404x2082. At notch 9 (15mm), the size is 1802x1091. An no I'm not kidding about that 1st number even though it seems really odd (vertical changes more than horizontal between eye relief change!). The engine is actually rendering 2404x2082! That would explain the low FPS with eye relief set all the way in. These are unscaled numbers (Camera Texture Scale = 1.0). At 1.5 camera texture scale the render texture sizes go to 3606x3123 for eye relief notch 1 (7mm) and 2702x1636 for eye relief notch 9 (15mm).
Guess we are already rendering 4K in some cases here! We're going to need better video cards. Time to invest in Nvidia and AMD.
