Pitool 1.0.1.258 Discussion

Have you watched as it installs? There might be a message saying what has failed during install.

@Heliosurge yes i watched it fully install with no errors 3 times so far and restarted PC after each with same message.

Sorry to hear. If redownloading and reinstalling not working likely best to at this point to file a support ticket.

Hi. Is there any benefit to use 144hz firmware if it’s already hard to reach 90fps in game ? (I play rfactor2).
BTW is there any benefit to use the virtual link port for the usb cable ?

If you can reach stable 60 or 72 fps but not-so-stable 90 fps it might be beneficial to go to 120 or 144 Hz. Because then you could use smart smoothing and get more real images per time rendered (smart smoothing renders every second image and interpolates the rest). With 90 Hz and smart smoothing it would fall back to 45 really rendered fps. But for games where you can maintain 90 fps but not 120 or 144 fps, the 90 Hz mode might actually be better.

Thks, I don’t like smart smoothing that much. On cars games, it adds too much artefacts, and it reduces the driving precision…

Another way to ask the question : Is the following statement true ? : because we don’t have G-sync or freesync, the more Hz the headset has, the more chance we have that every drawn frame will be displayed ?

If you render <= 90 fps then you should see every frame with 90 Hz. Latency might be a little lower with higher frequency. But then particularly Vsync has to be off…

Thks. I think I understand the whole matter, I will try it.

@Heliosurge once i plugged the HMD that installation error i mentioned before disappeared and to my surprise i see a 120hz option now, upon further checking my HMD serial number it starts with 203 so i guess i can flash beta to get 144hz but not sure, what do u suggest regarding benefits of 144hz firmware?

I don’t know to be honest haven’t tried the Alpha firmware. Need more input from those who have. Honestly though they should have imho released at least a beta firmware by now.

Agreed, Since the 144hz had some profiling issues.
for my 203 headset at least, it was not aligned properly.

been waiting on an update for it, so i can swap to it.

Oddly, though I used the 5k+ in 90Hz for almost a year, I can no longer stand the FOV shape. It’s like a projected rectangle. 120Hz and 144Hz are egg shaped and more natural to what the human eyes FOV is shaped like IMO. For that reason alone, even if I cant hit 120 FPS i dont change it.

  1. Does 144HZ change the IPD ? I struggle to find a good setting while never having any issue with that…

  2. When will a new pittool be released ? On rfactor, I still struggle at 50% of GPU usage ^^

noob question… what is the best way (right etiquette) of upgrading/downgrading pitool? Uninstall then remove folder from Program Files(?) …and stop service(?) restart after uninstall… a bit confused on whats required to do it the right way. I’ve seen someone mentioning that nothing is required - just install the new one over the old one.

I just install the new one over the old one. Downgrading might need removal first (but I’ve never done it, so I can’t offer advice for that).

I agree that you can usually just install one over the other. To be safe before running an upgrade I always do this:

  1. Ensure PT is not running and the headset is turned off
  2. Better still, unplug the headset from the USB and Display ports to be 100%
  3. Run the PT update
  4. Reboot (probably a service restart is fine but hey)
  5. Connect and power the headset and check it is picked up by PT
  6. Reboot again (probably not needed / service restart enough but hey :slight_smile: )
  7. Check to see if things run better or worse than before :wink:

You can go back as far as PT 245 without having to flash older firmware (assumes you are now using firmware 255).

While not necessary to do a clean install meaning just uninstall and install earlier version, I had found I actually had to do a clean install to gain performance back I had lost in a PT update. ymmv

To do a clean install:
1 turn off the 3 Piservices running in Task Manager.
2 uninstall Pitool in Apps and Features (this will remove the Pimax folder in
c:\ Program Files folder)
3 delete the pimax folder in c:/Program Data folder
3 delete the Pitool and Pimax folders in c:\user???\AppdData\Local
4 delete the Pimax folder in c:\user???\AppdData\LocalLow
5 delete the Pitool folder in c:\user???\AppdData\Roaming

Reboot and install earlier PT version.

great info guys… these should be pinned somewhere - unless it IS pinned somewhere and I havent seen it yet lol… I just got my 5k+ a few days ago and been having issues with keeping constant FPS with a fairly high-end system (9600k @5.2 + 2080ti - custom water cooled). I tried almost all combination of settings with no luck. Then I downgraded to what Ive been reading was the last 99% stable build [197] and had major stutters - unplayable. Tried 253 and got the same thing. So, I thought i was doing upgrading and downgrading wrong. went back to 255 and everything is ok but subpar performance. Excited to try 258 today and see what it does… fingers crossed. thanks for your help

Smartsmoothing adds a way less artifacts in 144hz mode than 90 or 120hz thats why I’m using 144hz/72hz mode for most modern simulators. ( ACC, PC2, IL2 , Dirt Rally 1, 2) Mind my 5k+ is 204 revision

Well ok I’ll do more test, thanks for the advice !
