Eye Tracking Software Fix

General discussion

Cool, I feel better knowing the whole backstory to how this project came to be.

Without this information I thought that you may have had access to source code in some official capacity.

I was just saying with the announcement of the VARJO AERO they supposedly have Foveated rendering working correctly. And that I wish my eye tracking worked and then your thread suddenly appeared.

I hope it works it would be great.

Question: So other than getting the eye tracking working correctly, does this improve the DFR compatibility with games or is this still down to Pimax implementation of DFR.

Also as Pimax updates their software in the future, is there a possibility they may overwrite your code or firmware and I would have to reapply it again?

Also since you modded their driver/firmware could you explain a little about what you actually changed to make it “better” (maybe that info would be too technical, I don’t know)

And it can’t even do that properly, its not heavy enough to keep the paper down.

Dfr is limited to what supports ffr.

Hello!, no it does not improve DFR compatibility as that is controlled by the game devs. as Pimax updates their software in the future they might overwrite the code. so yes you would have to re apply it again. and i wish i could explain it. but i am on less than 2 hours of sleep and frankly at the moment i cant even remember what i did hahaha

Not sure If I should be happy about this.

unless it means that general eyetracking DFR support in Pitool improves across both 7Insun an Tobii users.

If OpenXR support is added its a possibility.

Even if I jump through hoops and do the fix outlined in the post you sent, this doesn’t resolve the fundamental problems with the product, chiefly among them game compatibility, design (they interfere with distance to eyes, per NextGenVR’s review).

Go on Youtube, every review of the eye tracking modules is negative. I can’t find a single positive review:

Not just youtube, but the forums, and the product’s own product page. The product maintains a 3 star average review score by intentionally keeping up a duplicate completely generic 5 star score that seems dubious at best:

Average review:

I Do Think the technology behind it is awesome! Personally I dont think enough games support this , but I only have a handful of vr games. I works somewhat on dirt 2, only the right lens will work correctly as the left lens will dumb down the whole view in low resolution. Unfortunately my fave shield had to be modified. I didnt have any pads that would work well with my glasses so I had to use one thin and one thick foam so my glasses wouldn’t touch the eye tracker. I am more optimistic about the eye tracking for the pimax 12k. I might change my rating as I try using it for other games like Alyx and project cars 2. This did not work with automobalista 2"

All of the reviews are one star, there are four 5 star reviews, which are actually duplicates of two 5 star reviews:

I haven’t been able to use it because I have the pimax 8kx , but I don’t have the controls to use it.
I.m waiting for them

The Future: Brought to You by Pimax!

Way ahead of its time. I love the boldness of this company and the risks they take. If it were not for these risks it would take A LOT longer to get innovations like this. I do know with advancements like this you really need GPU headroom to get the most out of the products and all of its attachments. Technically speaking the eye tracking module should make it easier on your GPU and decrease the relative entry point, but I didnt get the 8K Pimax without full intentions of taking it to the extreme so its the sole reason I upgraded my PC with the 10900 and 3090. This company does rely slightly on intuitive users but rest assured there are guides everywhere if you need them. Take care and have fun!

If it wasn’t for these four 5 star reviews, which are actually duplicates of two 5 star reviews that you either created on purpose our have intentionally allowed to remain up, the average review score across 14 reviews would be 1.5 stars.

We aren’t stupid children. We are enthusiasts who typically have a lot of experience behind PC’s in general. When you treat us like stupid children you lose credibility.

This is why I have exactly zero faith the Pimax 12k will ever see the light of day and if it does it will do so with half of the features currently advertised.

Noted you haven’t bothered to try the Ops fixes. He does not work for pimax btw. Instead of going by reviews that existed before @guppyexpress ’ efforts to improve a dud to something functional. If you have an ET you have nothing to lose but time.

Presume your an Atheist noted. :laughing:

@pimaxUSA was right to move your ET comments to an ET topic.

You know, maybe you could try the fix in this very thread before you keep knocking the ET and bringing up reviews from way back before this happened? Instead of just bringing up a billion links all the time.

Nobody is arguing the thing had massive issues before. Should it have required a third party fix like this? Absolutely not. But it exists now so it’s better than a paperweight in my experience now.

Just stumbled into this topic. I had a conversation with @SweViver on Twitter yesterday, and he told me that the eye tracker is working fine these days and that I should just download the latest software/firmware from the Pimax website. Is this correct? If so, where can I find it? If not, has anyone actually tried @guppyexpress 's solution? Is it worth the risk? My eye tracker is still unboxed, should I open it? No turning back after that …

Could someone please clear this up for me?

Yeah I know - I meant besides the dev and the tester.

Yes I can confirm that, its working with both eye tracking modules I have here.
Just download the package from pimax.com under Support → Eye tracking.

The link is:

It contains this:

Now, run the firmware update (for help, check the Word document guide provided)
Install the runtime. But skip the old PiTool. Just run latest PiTool.

In PiTool, when eye tracking is connected, make sure the 7invensun Runtime is running (theres a warning message under the HMD icon in PiTool if runtime is not started).

Now just run the calibration, then enable DFR in PiTool and run any game that supports it. Works really well.

Its a 2-3 minute setup basically.

I have tested it on 5K Plus, 5K Super, 8K Plus and 8KX. All works.

It has never been easier than now.
Now remember, both the eye tracking runtimes must be running, here are the icons:

If its not running,you will see this text in PiTool:

Also, in AMCap, to test that cameras are working fine, set the resolution and fps:

I would suggest checking out Guppyexpres firmware as reports have suggested full 120hz to compare with.

Not sure why before they kept saying updates needed to be requested by pm.

Having all that said, DFR is far from perfect, it still have bugs, but it works really well I think, and faster than before if you ask me. Helps a lot with performance in Skyrim, Half Life and others, even on conservative mode.

If you use a high Pitool render quality such as 1.5 or higher, even aggressive DFR isnt really distracting and sometimes barely noticeable, since its downscaling the resolution from an already higher resolution. So you wont see that crazy shimmer at the edges as you would with PiTool 1.0 or lower, with DFR on aggressive.

Yeah, I have not tested Guppyexpres firmwares yet, looks promising Will do that tromorrow. Although, I see really no problems with 100Hz either. Its definitely fast enough for my eyes to not bother or even notice the DFR resolution areas moving if I look left-right-left very fast.

I have actually been able to get internal testing, allowed frame rate of up to 240 hertz!
