TestHMD - supersampling and Index image quality

For the fun of it, here goes - and I really tried to stand the exact same place every time (within millimeters) - but you have to walk a few meters/feet and restart the app every time you change res - I chose a distance of 3 meters, so this is not close (the images below correspond nicely with the images seen through the lenses - Index does not have issues clearly showing up to 1820x1820 pixels, which was the largest image size sent to the lenses - image quality may even be slightly sharper in the hmd as two images are combined into one by the brain):

Index res 100% (9 mill pixels)


Index res 200% (18 mill pixels)


Index res 300% (27 mill pixels)


Index res 400% (36 mill pixels)


Index res 500% (45 mill pixels)


For the size of the screenshots I got:

Index res 100% = 1137 x 1137 pixels
Index res 200% = 1604 x 1604 pixels
Index res 300% = 1820 x 1820 pixels
Index res 400% = 1820 x 1820 pixels
Index res 500% = 1820 x 1820 pixels

Image size in pixels seems maxed in this app at res 300% - but in Wolfenstein Cyberpilot res 500% is like 2250 x 2250 pixels. Maybe different apps gain differently from super-sampling. That said there is a noticeable difference between res 300%, 400% and 500% in the above images. The impact of going from res 100% to res 200% clearly is the most profound - I really never use the blurry Index res 100%.

Limiting image sizes to 1820x1820 may indicate that this app limits images to a res close to the panel res (1440x1600).
