What is it?


This is an information cluster app meant to reproduce as accurately as possible the Gran Turismo 3 heads-up display, with improvements such as higher resolution assets.


Track: Deepforest Raceway



Track: Deepforest Raceway



Track: Mid-Field Raceway

  • Custom Shaders Patch is REQUIRED.
This app will not run without it. This was made and tested with version 0.1.60 and has been tested with versions as new as 0.1.76. It may work with versions below 0.1.60 but I am not guaranteeing it.​
  • Content Manager is strongly recommended for ease of installation.
  • Automatic resolution detection — the app will figure out your current screen resolution at startup and place all the elements accordingly;
  • Imperial and metric units;
  • Scaling, from 50% to 150%;
  • Functional odometers, also available in both imperial and metric units — the total odometer will work by using Stereo's odometer or from Sidekick, so be sure to have at least one of these. It's fine if you have both; the app will try to fetch from Stereo's odometer first. If not present, will attempt to fetch from Sidekick;
  • Resettable trip odometer;
  • Tachometer ranges from 3,000 to 22,000rpm — redline is calculated at 90% of the car's maximum rpm;
  • Speedometers of 100, 200 and 300mph — 160, 320 and 480km/h, respectively;
  • Display of sector times, lap times, difference to best lap, record (personal best) and lap history in practice mode;
  • Display of position, sector times, lap times, last lap and best lap during races;
  • Instrument clusters for both chase and bumper view — GT3 originally only had these two camera views, so I extended this behaviour to match GT4 and GT5, where the analog cluster is available on the hood and bumper cameras;
If you have Content Manager, simply drag and drop onto it. After installed, the app will appear under Settings > Apps so you can enable it.​
Otherwise, you can extract the contents onto the game's root folder, as the zipped file has the folder structure already laid out. The apps folder contains the app itself, which is a GT3 HUD folder placed under apps/python. The content folder contains the app's icons.​
After installing and enabling the app, two apps will appear on the list:
  • GT3 HUD is the information cluster itself;
  • GT3 HUD Settings is the settings app to tweak some preferences.
After activating GT3 HUD, the cluster will appear on your current desktop.

Two settings are available and they are persisted in config.ini

  • Use Imperial Units? is a toggle that switches between imperial and metric units. Once changed, everything is updated automatically, there is no need to restart the session. All speed and distance amounts are affected, these being the speedometer faces and the digital readout, as well as both odometer readings;
  • Scale is a spinner that allows you to change the size of the cluster. When it is changed, the elements are repositioned accordingly. It allows from 50% to 150% of the original scale.
As well as a few options
  • Reset Trip Odometer allows you to zero the trip odometer at any moment;
  • Reset Scale puts the scale to the default value, which is 100%;
  • Scale HUD to Current Dimensions resizes the HUD to the current size of the game window. Useful in windowed mode after resizing it, in order to put the HUD back into place.
  • The TCS light is not blinking, what gives? Check what version of CSP you have. It will only work on version 0.1.69 and above.
  • The ASM light doesn't turn on even if I set Stability Control to 100%, why is that? From my experience, this occurs only on practice, where some cars will have stability control on 0% no matter what you set in Content Manager. I'm not sure why is that. On races it works as expected.
  • The ASM light doesn't blink. It won't. There's nothing to get whether ASM is being used or not. If that changes in the future, it's likely I'll update the HUD so the ASM light reacts.
  • Why does the 7th gear character look weird? While Gran Turismo 3 originally doesn't have any 7-gear car in its roster, I found this GT3 mod showcase video which inserted a 7-gear vehicle and thus, I attempted to faithfully reproduce the 7th gear number from it. So that's where it comes from.
  • I can't see the time difference between me and the first-placed opponent in the game, why? This has not been implemented yet. I am also pursuing a way to include the flashing car miniatures that appear next to the time difference. No ETA on this feature.
  • Why is nothing appearing in the replays? I made it that way. Not every piece of information that I use from the player's car to show the HUD is acessible on the other cars. So, to avoid any issues, I disable the HUD entirely during replays. I plan to rectify that eventually by making a separate, minified replay HUD much like GT3 itself does. No ETA on this one.
This is still a work-in-progress and there are more things to come. As much as I tested this in my own system and collected feedback from other people who tested it, this is still a first beta and it is high likely some bugs may have sneaked. Please be understandable of this.
Other than that, by all means, have fun!

This is awesome, haha. I like how the TCS/ebrake indicators light up. The checkpoint timers that pop up etc. great mod
Very good, But no tyre degradation and tempeature information, although one could say just use the assetto corsa app, some would prefer a more basic tyre display for quick drives
It is in my plans to include a tyre wear graphic identical to the one in Gran Turismo 3 itself.
Memory unlocked. Thanks for sharing!
Would be nice if these were all moveable.. I don't wanna look at all 3 monitors. but hope you keep working on them. they are good
It is in my plans to support triple monitor setups.
very, very nice tool for AC. Thanks for your work! But - how can i change the DISPLAY MODE? Whitch Key? Thanks and have a nice day!
If you mean changing between the analog cluster in the center and the one to the rightmost side, they change automatically according to the camera view.
Fantastic job!!!
Can move hud to video center?
Thank you!!!!!!!!
Hello, if this is due to a triple-screen setup, that you need to have the HUD in the monitor of the center, it is in my plans for the future to have support for it.
BEST HUD !!! (please finish the job , we need the map)
Nothing shows on screen
Awesome App, thank you!!!
Best mod, works instantly great job
I dont see the app.
This is a wonderful mod with amazing nostalgia, I played GT3 alot growing up, so it was a nice feeling for me. However I can't seem to get it to work at all, I've even tried multiple CSP versions V1.60 onwards and I'm not getting any visuals, the settings app works, but not the main app itself.
There have been a few people reporting this issue on the discussion thread and it seems it most of the ones who had this problem had it when there are multiple apps running. Most of them have been able to make it work by disabling them all and running the HUD alone.

You can check more details here if you wish -

I'm still in the process of investigating this misbehaviour, but regardless, I hope the thread linked above is of any help.
is there any way to remove the lap and placing in the top right?
No, they just change according to whether you're in a race or time trial/practice.
Amazing! Thank you!
I have a setup for racing with Sidekick etc... My second page is this HUD, for hot lapping etc... The GT interface is amazing.
beautiful nostalgia
I like it
I love this! Now I feel like I'm playing gt3 on assetto corsa.
