To me this device is the best solution because the weight is at your belt

It adds too much latency.
12ms more.
They say on their website.
The latency overhead introduced by KwikVR has been measured with our patent pending technology under 12 ms, guaranteed.

And what is the latency of your/most computerscreen(s)?
Is it a gamebreaker ?
All the other solutions are in the 3-5ms range. 12ms is far too much.

Too much for what? I played competitive with HP LP3065 (12ms screen latency) then switched to Benq xl2730z(144hz 1ms) . My stats bumped for 5%, later to 10% and just imagine speed of screen flicking while using mouse and keyboard vs VR. 12ms is OK for 80% of population.

I think he’s talking about more latency in VR = more nausea, because of the greater delay between physical movement and virtual movement, among other things.
I think OP mainly meant that having a belt-mounted wireless module would be best. And I agree; It’s common sense, and it’s what I expect Pimax to make.

I’m talking of motion to photon latency in VR, that has to be 25ms or less, better less than 20 ms; this adds 12ms more only for the wireless connection, a very bad think that kills presence.

Then don’t invest in KwikVR, simple.
Nobody should until they reduce it much, much more.
Q: What kind of Response time (in ms) does the headset have with all the upscaling etc?
A: motion to photon latency <15ms
With this system 15ms + 12ms almost doubles.

Not possible with 60hz
This does nopt apply. In VR it will simply make you feel sick! You can play at 25 FPS on a computer screen too. It will judder but that’s it. Play at 25 FPS in VR for a while and you will puke.
Positional tracking must be instant. If it is not (=latency) you will turn your head but the screen wont. This is very jarring and leads to sickness.
This is why 90hz are a big deal and pimax tries to reach it.
That being said the Rift DK2 had 75hz and it felt fine to me. Another sidenote: At 90 FPS the latency motion to photon is at 11ms. Adding 12 ms is huge - it is more than doubling total latency!

What isnt? A belt-mounted wireless module?
A belt-mounted wireless module? = Yes, and looks like it’s not working, no one should buy it, otherwise it can work probably, but still highly not recommended.
Just find wireless module with lowest possible latency or set it to = 0 = best VR experience.

The unit at your belt with shorter cable is imho the best solution instead the weight and wifi transmitter/receiver
on your head.
The latency has to be in the 3-5ms I admit.

The KwikVR receiver can be worn on a belt, because they use 5 GHz Wi-Fi, which can pass through your body. It has a low data rate though, and that’s why they need to use compression, which in turn adds latency.
TPCAST uses proprietary wireless in the 60GHz spectrum. That enables high data rates, making compression unnecessary, leading to low latency, but it also doesn’t go through objects. That’s why you need to wear the receiver on your head, and mount the transmitter high up to prevent occlusion.
I hope future wireless VR solutions will be standardized, e.g. based on IEEE 802.11ay, so they can be used with other future 60 GHz transmissions in the same room without interference.
The receiver would ideally be built into the headset, to keep the connections short, possibly with multiple antennas built into the headstrap, if it can be built small and light enough.

All the VR wireless systems, all of them, have a lot of compression.

might be a better method once Wireless AX comes out. but it is defiantly a step in the right direction, VR needs to go wire free, but without the cost of degraded immersion or nausea.

Normally, compression will not be noticed at all.

You are right. I was misinformed in regards to TPCAST not using any compression. They actually use WirelessHD.
