I have used 132 (Pimax 5K+ 202)for a long time and it have worked well ( I only use iRacing).
I decided to update 262 (FW V22.214.171.1244) to see if there is improvements and better performance.
Performance was a lot better, maybe 25 more FPS, image quality is good and even colours seemed better.
BUT, there is a BIG problem. When I first tested 262, I immediatly noticed that something is off. When driving, I got this feeling that I’m not there. It was more like I was looking into to world and not being there. Really hard to explain. I switched to 110 Hz mode and it was a little better but the feeling did not go away. Then I tested 72 Hz mode and that was terrible, totally unusable. I have had DK2 in that 75Hz was not a problem.
I have D-Box motion platform and I also noticed that car movements inside HMD was a lot more pronounced than before. In 72 Hz mode, even just sitting in pits the engine idle made the whole image jump.
Also, I can’t get IPD setting to feel correct with 262 (I have 68 IPD).I got a lot of eye strain and headache.
So, I decided to unistall 262 and install Pitool 132 but keeping FW V126.96.36.1994, things went back to normal right away.
After driving for a while, I though maybe I was imagine the odd feeling with 262 and installed it again. The same odd feeling was right there. I was trying to see what was different between 262 and 132, but I could not find any clear reason. Maybe, even @ 110 Hz in 262 the image was not as smooth as 90 Hz in 132, not sure.
I also tested 197 and that did not have this odd thing. So, I’m going to use Pitool 132 with FW V188.8.131.524, this feels best combination now.
With this combination 72 Hz mode was ok.
Staff, could you explain what could cause this odd behaviour. Did distorsion profile changed ?, did IPD setting changed ? or something else? I have ordered 8KX and if this same thing happen in that HMD, it unusable for me.
Could this be the same thing that Sebastion was complaining about 8KX ?
About IPD adjustments.
When changing IPD with mechanical system the scale does not change but when changing in software scale change. Why is that, is that correct ?
Sorry for long post.
