Connecting a small low resolution monitor also delivers a load of extra performance. My PC was built for VR exclusively and uses a 13" 800 x 600 TFT as its only display, which i could luckily rescue, before the IT threw em all in the bin.
To me (sorry Frank_G), this sounds like bunkum. You could run a regular HD monitor at 800x600 and get the same effect, if any.
The only difference I can think of is a small reduction in video RAM used by a smaller frame buffer. If ED is running at 2160x1200 resolution for the Rift, down-scaling for the monitor window takes so little of a modern video card's resources its not even worth measuring.
If it works then that's fantastic - but if so, why have trusted hardware sites like HardOCP, etc not found it? Please explain if I'm horribly wrong. :S
@requ1em - sorry mate but I cannot agree.
Running SS=0.65 in ED slaughters, and I mean,
slaughters the overall image quality. Knocking 1/3 of the pixels out cannot do anything but.
Yes it pushes frame rate up, but the loss is too great for me. Any improvement is purely subjective. It does sharpen text and lines/edges (because if you over-render using the debug tool first, the overall effect behaves like an Unsharp Mask) but all other image quality metric are severely degraded.
Texture quality, mipmaps become useless, AA in the oversampled image is ruined etc.
Some describe and like/prefer the 'crisp' image quality, and if it works for you - great!
Everyone's mileage varies - for me it's just horrible, significantly worse than the normal debugPD=1.0, SS=1.0 ED defaults. I consider 0.65 SS damaged, and the high frame rate doesn't make up for it. But its cool that FD left the option in there, so players can make up their own minds and balance fps vs. image quality.
@Frank_G - on a headless setup - starting up without a monitor shouldn't be an issue. You could start the PC and simply not have the monitor plugged in.
Windows would probably realise you don't have a monitor, and if you looked in Device Manager, it would probably reflect that, but does the nVidia video card driver aware that no monitor is plugged in? I bet it produces video whether or not a monitor is actually installed or plugged in. Any check would degrade performance, and no gamer is likely to use a headless setup (or use a 1080GTX in a server, unless... bitcoins perhaps).
Headless installs are only really common in the server world, where remote login is de rigeur. But should work fine for any regular PC. Could also remote log in from a second PC if you have one there.
Educate us!
