there are some pros and cons using the 5K+ and 8k latest pitool 220.127.116.11 driver.
I have been playing on Pitool at render 2.0 and Steamvr at 70% with the latest Nvidia Drivers (GPU is a Aorus GTX1080ti)
fps is increased in almost every game i have tried so far…
Alien Isolation, No Limits 2, Elite Dangerous, DCS, Warthunder
…and in some cases i was able to increase the graphics settings in game - especially in No Limits and War thunder!
the focus sweet spot on the 4k is better using this version of the software, before the focus was only in the center and only either directly in front of you, or slightly above the center or slightly below it. now it appears to be all of that area!
i am able to have both the old PiPlay (inc Dr Pi) installed as well as the newer PiTool at the same time
The IPD in the pitool is still not allowing ‘RL’ IPD - My IPD in RL is 68.3, but i have the Pimax 4k showing at 59.0 (the last Piplay i had it at 58.3
Ghosting is back … it is a little worse in this version compared to the previous version on PiPlay. only effects bright illuminated areas but it is defiantly noticeable - If @PM_Sean @Pimax-Support @xunshu are able to apply a similar anti ghosting algorithm from the last piplay to Pitool then it may help… or we just wait until Pimax are able to implement the hardware/software tweaks they mentioned in one of @xunshu post to improve ghosting
In the PiTool settings i was able to change the resolution to 25601440 which should restart the HMD and show the nice planet scene which is the Pimax Home screen, but this just went to a black screen? it never re-rendered the home screen, switching back to 19201080 then allowed the home screen to re-appear. Note you can see the ghosting on the home screen easily if looking at the sun above the planet surface!
I was unable to change any settings in Elite Dangerous as i am already running it at max quality, but i did take my ship to the high graphics areas and saw no missed frames or latency issues, which is good!
In No Limits, i was able to change all of the ‘Details’ settings to MAX (previously was Medium for all) and the game still ran fine, albeit at about 43fps, taking off some of the shadows made the game hit 60 and stay there!
DCS - this was always a killer for me (see my thread in Content area) fps in this game previously was around 35max. leaving pitool render at max (2.0) but Lowering the in game pixel render to 1.0 (from 2.0) and then setting all graphics to Med or High got my fps to around 45, that is including the cockpit as 1024 instead of 512
Alien Isolation not a higher FPS as such but the game did appear to be running smoother, this may just be placebo?
War thunder had a fps on start up of about 5fps faster than before, and the additional (slightly larger sweet spot) made the game nicer to play.
unfortunately the ghosting is a real bug bear for me, and i will try tweaking a few of the games to see if i can minimise it, but i think i may keep this pitool version installed for now.
