Can I disable the screen mirror on my monitor?

Hey everyone, I'm wondering if it is possible to disable the screen mirroring on my TV so that I have all the performance on the Rift.  I am not sure if the Rift was designed to send out both signals without it impacting performance, so if it was possible to turn the normal image from my television, I'd love to do it. 


Thanks for any help everyone:)

Rofl, dude, in that one area, my parents are awesome, they don't care about porn, they've seen it before.hehe  No, my curiosity is mainly to get higher framerates on the Rift.  I've been playing Dirt Rally, and have been benchmarking it for a few hours, and the highest framerate I got was a bit over seventy frames per second. 

It's annoying to no end that Microsoft made so many bold claims about DX12, how it was going to force better usage of multicore CPU's, and more importantly to myself, it was going to really affect the performance figures on machines using SLI or Crossfire, but of course, from everything I've heard and read on different pc websites, those features aren't there yet. 

Take my graphics card as an example, since its an AMD R9 295x2, were the claims Microsoft made about DX12, my dual GPU card should run more like a single GPU card, because they were claiming that you'd even be able to use an AMD GPU and an NVidia GPU together, pooling the VRam as one and then assigning the tasks between two cards according to the power of each, so one may get seventy percent of the work load while the other gets thirty percent. 

My card should be a 50/50 split, or as I've mentioned before, the tech should simply use one GPU per eye.  It would solve everything easily.  At least in my own mind, not being an engineer, it just seems logical.  Now, I've seen tons of Youtube video's where the people were using the Dev kit 2 and showing you how to mirror the screen to your pc monitor, so I assume that at that phase of development, every resource went to the Rift alone.  Why not allow things to be that way now?  I just wonder if they do it for the benefit of any friend that may be watching so that they get to see what your doing or how well your playing, but if there isn't anyone there, why waste that power?

The power is not wasted, like I mentioned above what you see on your TV or monitor is a simple mirror. The GPU is not redrawing the scene again. Dual GPU or more setups are tricky still and up to developers to implement correctly. Having each GPU send a frame to each eye causes a lot of latency and it all has to be in sync.

nope your still going to have to hide your vr porn

No you cannot. There is no impact to performance, it is an exact signal mirror from the GPU, geometry and shaders are not redrawn for the screen again. Think of it as a simple video feed.

Awesome explanation, thank you - I've been somewhat worried about the monitor

This may help someone ;")  I have noticed an huge improvement with my self-build machine (with less stuttering and better overall VR) by doing the simple trick below,  even with the best system I knew to build at the time (My Kingdom for a 'K'.. anyone get that? LOL)   this helps,  so surely it would help even more on a lesser system (?)   I SURE WISH I had gotten MORE POWER - OR the GTX 1070...   If some one could look at my system-specs below and tell me my bottleneck(s) I 'd be most grateful!)
SYSTEM: 
(
Gigabyte H270 Gaming 3 Rev2.0 MB,
Intel Core i7-7700 (No bloody A, B, C, or... K...),
16GB Corsair Vengeance LPX DDR4 2400,
 WD Black M.2 drive,
Gigabyte Aorus GTX-1060 6GB,
Power CTX 750M

so to try to wring more out of each game,  I do things like:
1) Change my 3 Monitors to 1.
2) Change my Resolution from 2560x1440  to 1024x768 (even 16-bit..)
3) Go into the NVIDIA Control Panel and the 3D APlication settings, and learn all the ones listed, how they affect VR (Most are best set at Applkication Controlled)  <--- On this step, if you can see the Oculus in the Multiple Monitor Setup screen!  Do optimizations while on THAT 'Monitor'!
4) Check and see! TURN OFF 3D Vision 

Hmm,. There's more,.  I have worked at Activision many years ago and learned to try to wring every conceivable ounce of power out of machines while building games in DOS in Autodesk 3D Studio (for DOS!)   I'll add to this as I think of the other things I do.

Anyone know if removing 3D Vision removes VulkanRT ? This prevents Lone Echo loading. I don't see a direct link to those files in the package.
