Forgot to mention my HMD & hardware
Pimax 5K+ (203)
Hardware > i9-9900KF / RTX2080Ti
So you switch from 253 to 260 with 144Hz on both ?
For me the image was completely distorted on 253 with 144Hz.
It may depend on the HMD model. Are you on a 5k+ ?
I tried 144Hz on 260 but I had an issue on right eye.
The low half of the right screen was shifted/distorted/wavering : As you can see here
Good Point !
I agree with that and I think most people here too.
When I bought my 5K + I didn’t think I would ever have 120Hz with a Normal FOV (Wich is already big compared with others same price range HMDs).
And today we are complaining that the 144Hz mod does not work !?!! - for me
We’re just excited to take advantage of the updates announced and as users we may be a little frustrated when it turn out to be imperfect or even worse than before.
I just hope that our enthusiastic feedback can serve the PIMAX TEAM, and thanks to their hard work they offer to us the best VR experience possible.
I am on 258 still but I noticed I have this kind of effect (ghosting like, resembles double image but shifted only by very little) with PP ON (and not 100% time, sometimes it corrects itself for short time but then kicks back in). With PP OFF (assuming game does not need it) everything is fine for me on 120Hz with Normal FOV. On 90Hz no problems.
120Hz is flawless for me on a SN203 headset but there is un-usable ghosting at 144Hz. Seems like an oddly small subset of users - most have no issues with 144Hz so I’ve been pretty silent about it. Halving the framerate with motion smoothing and having wobbles makes sense though, which is why I just keep that off always.
It almost looks like OLED ghosting, but like 5 times worse and on all colors. I doubt I could see much of a difference between 120 and 144 (90 to 120 was a huuuuge jump though), so I don’t care that much but It’d be cool to see it fixed.
This likely depends on which LCD panel model is installed in your headset. Apparently, they vary, which is why you’ll see discussions regarding the first 3 digits of the model number.
I am getting confused about which version to use now when I received the new 5k+ replacement for my RMA. The headset I received has 203 S/N, but it clearly has a firmware which is no longer compatible with my old v132 PiTool. (I had originally 202 and suffered the stutter on every PiTool version after v132 so I held on this one as long as was possible.).
Now I cannot even read the FW version from my new 203 headset with my old PiTool. Pimax recommends to install v260 and firmware 264, but from what I read here, it seems to have more problems then advantages (stuck brightness, framerate drop). What is the most conservative (=stable) version at the moment?
If I remember, you also had stuttering in ED with pitool above .180. I think pitool .260 is excellent and I have no brightness issue.
.258 is also great if you’re worried about the brightness thing. You aren’t going to perceive a difference in performance from .132 or .144 really, imo. You will compared to .253, but that’s just not usable to me.
I did not test 260, but I am running 253 and tested 258 for couple of days.
I would say if you are looking for “conservative” option, I had zero issues with 258, best image quality (smooth pacing) and default brightness of both 253/258 is fine by me. Issue with 258 was that the framerate was lower than 253, but 253 has flickering when game is in transition (menu loading etc) and jumping image, once in a while.
You made a great point above, it’s possible that 258 simply requests higher res than 253 (although I did not notice image quality changes, only smoothness and no flickering in 258). This definitely needs investigating Luckily, there’s a way to completely remove pitool and keep room setup, I can send folder/file list from my notes if needed.
if you still want to use your old firmware just install the pitool version you want and in C:\Program Files\Pimax\Runtime\dfudriver\p2.dfu will be that matching firmware
start C:\Program Files\Pimax\Runtime\Dfu.exe and flash the firmware
203 is still the same hardware as produced in early 2019 and delivered to most backers (like me)
pitool v132 had fw212 and came out around june 2019, so pretty sure i had this in my 203 headset before
Yep I’ve the latest firmware 264
So the problems I have with the 144Hz mode would be specific to the 203 series
I hope PIMAX has noticed this cause they were on the right track.
I should try again but I think I remember:
PT 253 (FW 264) 144 Hz: distorted picture (sort of fisheye effect)
PT 258-259 (FW 264) 144 Hz: picture OK (despite other bugs)
PT 260 (FW 264) 144 Hz: Sort of jaggy/shifted/distorted/wavering picture on the lower half of the right panel. The left panel and upper half right was OK
I don’t know what to say. I am lost on words regarding software engineering quality. Regarding Pitool. I’m a fan of the hardware but this must stop.
You’re torpedoing your efforts.
And it’s no user issue, or issue of different hardware configs, or similar. I have 4 different headsets, all work fine, except for the Pimax post-254a. The Pitool shows the same behaviour on another PC with totally different hardware. All other headset manufacturers properly manage this, 95% utilization, even Microsoft with their WMR… It is in Pitool. Neither a user nor config issue.
Also, with the returning bugs skipping version (Branching! Version history!! Clean coding!!), we see if a person is a “self taught programmer” or a professional. It’s totally unnecessary.
Pimax, get help. You can’t do it on your own, it’s evident since January 2020. Ask Valve. HP did that too. Please.
I just hope the 253 version still works on the 8KX when it gets here.
Is there an open source version of the 254 so we can get someone to fix the crash ?
