Codemasters Dirt Rally Plugin 2.0.0.3

Dirt Rally has been a great experience for me with motion and VR, i hope they will soon release a patch for runtime 1.3 of oculus rift. I'm pretty sure you will enjoy the game Noorbeast!

@Tim McGuire

The Dirt Rally motion has been shitting me up the wall for the last week, I gave up on it to be honest. No matter what I did the motion was terrible, really jittery and completely lacking in sway, to the point where I had turned off sway thinking it was bugged. Even still it was so jittery the only DOF's that would give any real feedback were Roll/Pitch but only if they were assigned most of the axis and surge/heave turned way down.

Finally today I feel I got some normal motion from it by turning the main level in the game managers profile editor down to 90% ( I played with 95% - 99% all still had weak sway caused by the overwhelming jitters)
At 90% the sway/surge effect aren't removed by the constant jitter, you can feel the movement of the car and the road surface again and still have a heave effect that relates well. Give it a try and see if that helps, I've yet to play around with it much more since first trying these settings.

Thanks for the tip, I'll give that a go when I get the chance. I wish I knew what was causing the values to not come out properly though...

So I reset all my tuning numbers and started again to test out the 90% level , these are the axis settings and tuning numbers. A lot lower than before on the tuning numbers and I added a bit of sway in the axis assignment. But the movement was really good, seat wasn't shaking like crazy on the start line and moves around nicely with sway/surge & pitch/roll all clearly present. Road surface is still bumpy as expected, but if you stop the car then it feels like normal engine idle motion rather than previous when it was all over the shop no matter what.

You had the same issue as me @Goatboy and @Tim McGuire

I found I had tuned my Sim too well. What I normally do to tune my Sim (after I have the axis set) is turn my main level down to 10%, then set my Tuning centre values to 0 and then go for a drive and try not to crash, while I am capturing the values in Tuning Centre. Then I save the values, turn the main level back to 100% and fine tune from there.

(If you try this method, make sure your main level is 10% (or lower) before you reset the value in the tuning centre to 0!! - First time I did it this way with main at 100% I got shaken so hard I struggled to reach my emergency stop!!)

What I found in DR was that the values are always moving and I had tuned them too close, so at the start line my sim was still shaking even before the car set off. Once I upped the values in the Tuning centre and increased the Axis %, I was getting much better movement.

My resulting values are very similar to what you have found. The actual output for the game is in the fractions on some of the values, heave for example can go between 0.0054 and -1.xxxxx, so of course the closer you try to get to those numbers, the more "sensitive" the sim will be to large jumps in those numbers.

I was trying to be tooooo fine. Clearly....

To me, it's as if the signal clips once main level is turned over 90%. I tried putting higher numbers in the tuning centre but it would only completely wash out the desired effect and just leave the jittery effect as if you were driving a solid suspension car down a cobblestone road. Tuning it further today, a test would be at the start line, if I rev the car the seat motion should settle, and the motion when the engine idles shouldn't be excessive. I wasn't able to achieve that whilst main level was anywhere between 92%-100%

Are any of you actually monitoring the Axis output while running ? Might help you guys isolate and pin point sketchy forces. Yes Dirt struggles with Sway and somewhat for good reason. The car is on Dirt therefor its Constantly wanting to go sideways with the way you steer into corners and such I spend a Bunch of time on Sway one day and determined its in General Super Sketchy data and there's not much we can do about it, Even filtering the crap out of sway didn't help. Add in the fact that the Physics engine works in such a way that its Very rarely a Solid Positive number or negative number for a very long period of time in the data, Surge for example again, will Constantly want to twitch due to how the engine is coded with the On throttle Off throttle effect, The Pre start and Post "shake down" modes prove that DR doesn't really care about what data is being output at those points.

Traction loss seems to work The treat in DR, with a setting of 18 on my MIN/MAX, i can sit behind buddy driving and watch the Utter perfect linearity in the TL axis, the Big Hand brake moments is a Very quick moment and feels Utterly Perfect.

Barrel rolling in this game is a FLIPPING INTENSE feeling, First time i happened i near crapped my pants. The Feeling of weightlessness and the SLAM SLAM as the 2 sets of tires slam the gravel as it goes over again, BAM BAM, Light feeling, BAM BAM, light feeling, BAM BAM as the car cones to a stop, your left in utter amazement as to what you just felt/seen.


As for tuning with the Main % slider. Im not a fan of that, your Physically removing data points from the games data and I personally want to run thing's at 100%, and not miss a Single data point.

600/600 on JRK and 100% on Profiler.......If you got it, Run it!!!!


Im still baffled how i can run a heave of 13-15 and get perfect surface detail, and some of you guys are around 1-2, which makes no sense to me.

Yes I'm monitoring Axis output.

Surge shakes like someone with alzheimer's when main level is set to 100% and tuning center numbers are in single digits (this is all whilst car isn't moving and I'm standing on the brake). If tuning center is set higher for surge like at 10 for example, jitters are reduced slightly but so is the influence surge has on motion, ie no movement is experience at the seat when on and off the throttle or whilst braking.

With main level at 90% I've been able to tune it so I feel engine revs , brake and throttle surge, sway whilst turning in , the pitch and roll of the road and road surface but the most fun of all...jumps. And yes JRK are at 600 , PID 37/0/50 and only shutdowns are coming from a soon to be replaced PSU. It might not be how you've done it, but as you said, the data is in general super sketchy, this is what works best for my setup.

Thank you so much !!

Is the plugin source code avialable? (If not i try to make a plugin alternative)
Its not working in my computer, the config is OK, the port 4123 is sending data... checked with netcat... redirecting port 20777 to 4123 with netcat or Codemaster Proxy not work

Any advice?

Thanks and sorry for my english

Maybe try to first follow the setup procedures.

Uninstalled all soft, deleted program files & appdata files, reinstalled all soft & plugins with the same procedure... and no luck, other plugins work but not this
Disable antivirus, firewall, and others but nothing...

Checked the bytes in UDP 4123 with my own soft, so the game is patched OK runing with extradata 3 in 4123 port
The dash config is enabled & 20ms rate

Shows Game Running & Dash load the profile when launch the game, but not show data...

Are special steps for this plugin? or something to check? or i am missing something....

My windows installation is clean.. only used for 3 or 4 games in steam...

Hi ive not needed to use codemasters proxy server for a while i run MOTION and GI-MAX at the same time with these lines

<udp enabled="true" delay="1" port="4123" ip="127.0.0.1" extradata="3"/>
<udp enabled="true" delay="1" port="20777" ip="127.0.0.1" extradata="1"/>

in the hardware_settings_config.xml and works great hope this helps.

Thanks

Did you guys solve your issue? Just acquired Dirt Rally and experience the same effect: I'm shaked like crazy on the start line and then very random movements...

I've read the whole thread, and applied why worked for others like switching the OS to English (UK)... But nothing really works. While reducing the main level at 90% allows to get rid of the shaking on the start line, the rest of the motion still seem to be mostly random. Any help appreciated.

did you go in control panel - region and language and change Format , Location tabs and on administrative tab the Language for non-Unicode programs , into English

or did you change your OS language into english.
are you having the same issues with other games too?

Thanks for trying to help I did the steps you indicate, didn't touch the OS language so far (already in English anyway).
I don't have any problem with other games: Assetto Corsa is set and tuned and give great sensations, Dirt 3 if less realistic, works also well.

I have reduced a lot my percentages for Dirt Rally, especially for the Sway and it's better already, though I have now more a feeling of the road surface than centrifuge forces in turns.

Ok, so I made a video to explain what happens:


As you can see in the tuning centre, some values (only Sway, Surge and Heave) reset to zero from time to time. Increasing the delay in hardware_settings_config.xml doesn't help, the proportion of "0" within all the values remain the same, no matter how often we receive these values. FYI, I have applied a large filter on my axis while recording this video to avoid being shacked in every direction.

I have no idea where the problem comes from, but I'm pretty sure this could be filtered within the plugin... @value1 , I don't have access to its code so I can't do it myself, but I would if I could.


Any idea of what I could look at is much appreciated.
