Judging from the monitor screenshots of Fruit Ninja game that Tested was playing, it looks like the image output is highly stretched. Correct me if im wrong, but I think I finally understand why it “looks stretched” on monitor and Im sure its not streched while looking inside of the VR HMD .
There are simply several ways to project/output a specific FOV, like Rectilinear, Cylindrical etc. Here is an example how a game with 160 FOV looks depending on what projection is used:
On the monitor, while Tested played Fruit Ninja, obviously the game was projected with Rectilinear FOV, thats why it looks so ridiculously stretched, while in headset it has a different projection (maybe cylindrical) plus some optical corrections.
What makes me think this is the case, is because I encountered the same issue while playing Half Life 1 with a VR mod (check my latest video) on HTC Vive. In VR view it looks perfectly scaled and correct. On the monitor, the game output looked stretched and exactly as the Rectilinear example in the image above. Just like the Fruit Ninja does on those screenshots.
Its just my thoughts, so im not 100% sure but I belive this is the case. Let me know what you think guys!
As of today people are still claiming it’s stretched inside the HMD, read the latest Tokyo demo reviews posted overnight. Pimax claims it’s due to wrong IPD but they did not manage to fix the IPD for the Tokyo demo … So we still don’t know for sure if it’s indeed ‘just an IPD issue’ like Pimax claims.
“I just tried Pimax 8k (not X) in Tokyo at CEATEC.
Before I start, let me preface that the unit I tested had a broken IPD adjustor, so I was playing with IPD that was too wide, I estimate 7cm (instead of 6cm).
I was given The Blu, which was great as I’m familiar with how it looks on other headsets. Brightness was what bothered me the most, as this is unlikely to be improved until release. I’m used to Vive brightness and colors, and Pimax seemed to be lacking in brightness and vibrance as much the Oculus, and possibly even a tiny bit more, can’t say for sure. But the vibrant and bright joyful experince of the rift in the blu was definitely diminished as a result.
SDE was almost non existent, which was pretty amazing to see. But lack of proper supersampling didn’t make the actual experience any sharper than it is on the Vive with proper supersampling. However, given the size of the pixels themselves, I believe that with proper supersampling, this headset has the potential for mind blowing sharpness. This is the main reason I will not be cancelling my 8k X Kickstarter preorder.
Unfortunately, they still haven’t fixed the distortion issues around the edges, so everything that’s not in the middle of the view gets distorted when moving your head or walking around. This causes the world to appear unstable, totally breaks any sense of presence for me, and looks like something that would cause me motion sickness if I didn’t already have very strong VR legs. However, since this seems like such a big deal, and after reading what Doc had to say about it, I belive this is something that just has to be fixed before release, unless they want Pimax to be a complete trainwreck.
Binocular overlap was a bit unusual, but I’m guessing I could get used to it. The increased FOV was not as big a deal as I was hoping it would be. Might be because how binocular overlap is handled or because of need for more vertical FOV.”
Apparently PiMax only has the one prototype and is moving it around to the different shows. I think the sooner we get to release date the problems with this prototype will be fixed. I’m sure PiMax is listening and working on the problem. They know they have a lot at stake here.
I’m sure they will. looks like they are going to every show they can.
Yata_PL, I hope that it does NOT require a “monster PC”, if it will run great with a mid range pc the better. This is what is implied by the kickstarter specs. Of course the 8k X will need a powerful pc but it won’t be out for awhile.
Something else to keep in mind is that as much as we want a perfect headset, it just does not exist with the current technology that is available. PiMax has the most advanced for the money right now and is far ahead of the competition. I will be happy to tolerate a few shortcomings to further the progress and promote competition.
I do hope they fix the periphrial issues as the latest review made it seem a most imminent issue alongside brightness, stating only in the middle were things not warped. I’m also concerned about the vertical fov not being big enough as mentioned in the review. I’m still very excited to get it, but tha5s not to say I’m deeply concerned here.
by “monster PC” I mean PC with enough power for a supersampling to compare a differences between Pimax 8k and Vive,
Pimax “demo laptop” specs is unknown…
All of the reviews I have seen involved ONLY playing games. I have not read any reviews yet of someone using the 8k for movies of any kind. Since that is my motivation for this headset I want to know. If you know of some reviews for video let us know I want to read them. I get that everyone has been impressed with the FOV and lack of SDE. Two main issues to me. This latest one is the only one I have read that mentions the brightness in a negative way.
The tested review. 2 people that actually own all other devices and can give an honest comparison have clearly stated they would not recomend it for gaming over whats available to date. They suggest the clarity would make it good for movies. Your correct though the aspects have not been proven for video viewing
surely you know them already. They also claim that the images are deformed at the sides. However they say the diving sense is superior to other HMDs. From what I understand the new Pimax are a generation ahead, but still too immature. We’ll see.
