Thanks Kianweic. Was reading through some review. Does not have positional tracking, only runs at 60 fps. But at 1920 x 2160 per eye (4K full), its a huge jump from Rift and Vive. Most review say the images are nice, and screen door effect almost non existent. At USD 339, I'm kinda tempted.

That review is missing the point: he said that this 4K VR headset is his go-to headset to use for movies and virtual desktop. But therein lies the problem - if you're using movies, you might as well use HMDs like Sony HMZ-T3W or something that is meant for movies, those also has perceivable screen door effect/pixelated looks. For Virtual Desktop, that requires moving around, and with only 60Hz refresh rate, and at 4K wraparound render, unless you have a powerful PC, you're not gonna like the stutter. VR isn't just the visuals, it's  a complete package of visuals, positional audio, controls in smooth virtual UI working in concert. Having just a 4K display but missing smoothness and, what kills it, a dim 4K screen, is a dealbreaker to me.

Thanks for your opinion. I don't plan to play any games that requires me to move around (at least not for now coz my PC is in my room with limited space, plus I think my wife might go bonkers seeing me standing up moving like a headless chicken). If I do buy this, it will be playing project cars or some other VR games that I can just sit in the chair and play. I have gone through some other reviews, so the 4K res is what I'm really excited about. In my case, I prefer higher res than faster fps.

Oh man, you do know that the essence of gaming in VR is higher fps, right? Anything lower than 90, it'll be susceptible to make you sick. If you have access to a VR headset now, try pushing pCars under 90fps and see how you feel after that. It's the silky smoothness of your perception in VR that what makes VR works.

Some graphically intensive games like Adr1ft, in its earlier stage, makes people violently sick. Because the game constantly drop below the comfortable threshold limit of VR experience and turns you nauseous.

I'm firmly in the "higher res > higher fps" camp myself, but that only applies to static 2D plane gaming, not VR. Even losing your position in VR space, like when the sensors determining your position in 3D space starts acting up, that alone can make you sick. Try playing Samsung GearVR  with a phone that is overheating and watch the framerate spike up and down on that game, and see how you feel after that.

SteamVR (where your pCars lives) has set the comfortable limit of 90fps when using any VR headset. Any frame drop below that, it utilizes reprojection method to halve the frames down to 45fps while attempting to maintain smoothness. Think of it as V-Sync for VR. But pCars game engine is dynamic, the frames go up and down, and especially when you're trying to push that game to 4K, you are not gonna be able to maintain framerate stable enough not to make you sick. Even I myself had to drop settings to 1080p and Medium just to be able to play pCars somewhat comfortably on my rig.

If a VR game is static and no movement is present in that VR space, that not VR. That's like strapping a TV to your eyes. That's a HMD. HMDs like Vuzix or Sony's own HMZ series. Anything that requires rendering movement and position in VR, in order to have a comfortable experience in VR, must not drop below its said threshold. 90fps for Vive and Rift, 60fps for PSVR. And these are of lower resolution than your PiMAX, and even the most powerful rigs out there can barely keep up with that requirement. To take advantage of your PiMAX VR, running it at native 4K (well, split 4K at 1920x2160 each eye), if rigs connected to Vives and Rifts can barely cope, what do you think if the eventual outcome of your PiMAX?
*
Ahaaa, thanks for the info the pCars. I did not know that if the fps drops below 90, the game will slash down to 45 fps. I thought I would be able to set it to v-sync 60 fps. My rig currently can do pCars 4K at 120-130 fps clear weather, 85-100 fps in storm weather, all settings max out, SMAA high except grass low. But since I only have 60 Hz 4K monitor, I only run my games with adaptive V-sync, which not a problem and I get 60 fps constantly, no drops. So I thought I could well get constant 60 fps 4K too if I get the Pimax. But now that you said, its either 90 fps or 45 fps, guess that would be a problem coz Pimax only runs 60 Hz. By the way, can you tell me if pCars supports SLI in VR mode?

I guess the motion sickness problem will be bad if fps goes up and down, but maybe it won't be that bad if can get constant 60 fps (some reviewers say, matter of getting used too).I don't know, coz never tried, but I think 60 Hz its okay too, since PSVR is 60 Hz. Anyway, I believe VR headset experience also depends on our biology, and how our body cope with motion sickness/ perception of movement. Some people can, some people just can't. Just like some people are perfectly fine sitting in boat pitching and yawing, while some just empties their stomach. Or like some have no problem enjoying the window view from inside a moving bus, some already holding a paper bag. And I have an example very close to me, my wife. While I can go through the full Avatar movie on my home 3D TV, my wife won't make it past 10 minutes with the 3D glasses on, and its LG passive 3D, think could be worst if active shutter type 3D. I can drive up 3-4 story high circular parking ramp at decent speed, she'll be complaining of dizziness after the 1st level.

The only thing stopping me from plonking on the Pimax is my confusion on its refresh rate. Says it runs 4K 60 Hz, but it only uses HDMI 1.4b. I thought we need HDMI 2.0 to run 4K@60 Hz???? If that confusion can be sorted out and it really can run 4K@60 Hz, I'm almost certainly plan to get one. And if I do, and start throwing up nasi and mee goreng on the floor, I'll share my experience.

Let's put it this way: my twin Titan X Pascals cant even do 1440p pCars in VR above 90fps on Vive or Oculus.

Ha ha ha Damn. With my GTX 1080 SLI, I guess I better ask a snail to draw the images if I have Vive or Oculus. Thanks for the heads-up. Found Pimax forum here (http://forum.pimaxvr.com/c/site-feedback) and got some interesting info.

Answered my question on the HDMI 1.4b connection. So, while the Pimax does have a 4K LCD (forumers claim its from Igzo) running 60 Hz, the PC/ GPU side actually runs the game at 1080P@60Hz, and Pimax upscales it to 4K. No wonder feedback so far says the frames are decent to smooth even just using a single GTX 980 Ti. Coz the PC is only running 1080P. I guess the only time Pimax actually runs native 4K feed, it's in the movie mode, but running at 30 fps only.

Feedback too has been a mixed bag. But those buyers who already had CV1 or the Vive did commented that the Pimax visuals looks nicer because of the higher res (no SDE/ lens fresnel). Some claim running SteamVR with supersampling helped increase the quality a bit more. And some are trying to work on some software tool (chroma 4:2:0 subsampling which I dont understand) to force 4k@60 Hz or 1440p@60Hz over the hdmi 1.4b to Pimax.

I can't afford Vive or Oculus, and now that you said even your Titan X SLI is crying to churn out the fps in VR for Oculus and Vive, all the more reason I can't afford any of those 2. The Pimax at USD 349 with the headphone, still better than and cheaper then getting Samsung Gear VR with Samsung handphone. And that it only need to run the game at 1080P@60Hz in VR, which I think my GTX 1080 SLI should be able to cope well enough. We can have good laugh when if I puke.

If you do puke, same rule applies as when you about to go on rollercoasters: dont go on it on an empty stomach. Muntah angin is no joke, and if you kena that while touring a theme park, your whole day will be ruined. Don't go in on a full stomach either, that's like serving a full cup of coffee to the brim of the cup waiting to spill. Just have something and hope for the best.

Bought it through Lazada RM 1.3K. Yes, it doesn't have positional tracking, but like Fluffy said, can buy Nolo. Bought to watch 360 vids, 3D movies. Only tried playing Project Cars. No intention to play games with positional tracking for the time being. I don't know how the images compare to Vive or Rift, though reviews said its better because of the higher res.

And yes I knew Pimax 8K is out, but not willing to plonk that much money, plus I guess its takes a monster PC to drive VR with that kind of resoiution

Just to share my Project Cars 2 VR experience with my Pimax 4K HMD.



Video captured using my phone of the MirrorView on my main PC monitor. Always loved playing PCars but VR sure made the gameplay a lot more fun.

just curious what gc are u using?
also was there any drifting of the headset?

ha ha ha disqualified coz driving main2 looking hear and there. Just to show the VR experience looking around.

I'm using GB Auros GTX 1080 Ti Waterforce Extreme Edition. So far no drifting with the Pimax. Read that it use to have that problem, but newer firmware and the PiPlay software updates solved the problem. But there's some ghosting from time to time

Ha ha ha well even with those settings, what you call a bangsawan GPU just barely able to maintain 60 fps. Up the settings a bit more, and it will drop below 60 fps.

Pimax resolution is at 1920 x 2160 per eye, thats like 8.3 million pixels that the GPU need to churn out in VR (which my understanding more punishing than normal monitor). Vive and Rift in the other hand is at 1080 x 1200 per eye (total 2.6 million pixels). That's a lot difference. Even as you said, using SteamVR with Pimax res locks at 1200 x 2160 per eye only, that's still still 5.9 million pixel in total, still more than double Rift/ Oculus. And in my PCars 2 setting if you see, I maxed out the SuperSampling, which also very demanding on the GPU. I think the fact that Pimax has higher res, makes the any changes to image quality more visible.



When I got my Pimax, I was using GTX 1080 SLI but unfortunately, SLI dont work in VR. The single GTX 1080 just cannot cope with the settings I liked while maintaining decent fps, so that's why less than 10 days after I got my Pimax, I decided to swap the 1080s with a single 1080 Ti. If only VR supports SLI, I think the new Pimax 8K will only be good for watching movies, coz I doubt any single GPU now is powerful enough to drive VR games at 3840 x 2160 per eye.

I'm sure GTX 1080 Ti can run Dirt Rally at max setting with no problem.

ooo..did not notice is Project Cars 2.. i only have the first one so the PC2 sure looks better but need more demanding spec

Yup the Dirt Rally sure can run flawlessly on ur spec..the graphic is still ok la.. they are using older version Ego engine even older than Grid 2

Sadly the latest Dirt 4 dont have VR support yet..No VR, no sale for me  biggrin.gif

I used to work in Codemaster before as a game artist involve in Grid, Dirt 2 and F12010

No problem bro. Whoaaa you worked with Codemasters before. Damn. Do you like get free games from Codemasters?
