I bought this computer exclusively for gaming. In my list of purchases there were HTC Vive but I think that for a spending of more than 800 € the experience must be definitive without having to hope for future updates. Whoever uses HTC Vive judges them as HMDs who suffer from all the defects of a first generation:
Screen door effect
Problem with ergonomics
I repeat: the price for me does not justify these defects. So I bought the Pimax 4k. They price is not low ( = they are not considered a product that can justify its limits because of a low price). Also the difference between Vive and Pimax is evident. And I think it is justified the price spread between one and the other.
On the hardware front, there are games such "elite: dangerous", "project cars", "Assetto Corsa", etc., which are not born only for virtual reality. Their graphics are not designed to run a very high number of frames per second and a constant number of FPS is essential in HMD because otherwise you can feel nausea. So with the above mentioned games I noticed annoying slowdowns that make the gaming experience painful. Then i started to understand what settings change and where to start with the Pimax and SteamVR, and now Elite Dangerous and Assetto Corsa are great! BUT i have a nVidia GTX 1080 Strix!
I removed from my Pimax the blue filters, the filters the Pimax says that protect from blue light but seem to have a blurring effect cut function. With the blue filters the Pimax screen is very dark and the colors are "dim". The Pimax screen is a unique 4k lcd monitor. It is splitted halfway through software. The fact that it is an LCD makes it worse than the OLEDs because there are a "ghosting effect" if you move fast your head. But it is not a problem after few time.
I used the piplay version 1.1.92. It's old but it's the one that guarantees the best performance in terms of image and FPS. But it also has defects. The interpupillary distance setting is incomprehensible. It does not respond to the values you can measure. I have an IPD of 63.5 and use the pimax with a setting of 53.
Pimax lenses force your eyes to focus at a distance of more or less 20 cm. Those of the htc Vive instead make your eyes working by focusing at a distance of two meters. The effect, with some glasses, is a eye fatigue when using the Pimax for a lot of time.
I added a foam mask because the Pimax does not have enough. When you hold the HMD Pimax very close to your eyes the field of view decreases (perhaps 75%, depending on the distance between the lenses and the eyes). When the distance increases the FOV grow. Also if you have glasses is better to have more space between your eyes and the screen.
There is a lot of drifting with the Pimax gyroscope. So much to oblige you to keep the keyboard at your fingertips to make a fast recenter (in games that have this feature).
Compatibility between oculus and Vive games and pimax is not at 100%. SteamVr work. But if you need to try external software compatible with the two most popular HMDs, it's not said that Pimax works.
NoloVR AT THE MOMENT DOES NOT WORK WITH PIMAX. I'm writing it because I decided to buy the Pimax only after seeing the presentation of NoloVr. I also bought them, but I did not get here right now. Anyway in this forum there is a dedicated thread.
After all this, do I recommend the Pimax? If you're ready to work on the HMD to make them work as you'd like, and you have 330 € to use to make this kind of experience (with pros and cons), and if you want to buy a new GPU, yes. But the Pimax is not cheap for what offer.
I think that virtual reality is a nice thing for bigger, more powerful computers compared to mine, for HMDs with oled screen ,higher resolutions and good FPS performance, for optimized and good games (which are now few on pc). The Pimax in 2017 is a good compromise, as long as the engineers work to fix its current limits.
