Ah, that's the Mk1 (which will also be good to have a decent mod of).
This is the Mk2:

Jokes aside, we could make this to a good mod with decent help, needs many improvments, like a better cockpit etc. etc.

Did this mod work for you? My version crashes every time I tried the car.

Hello,

All the unfinished Tomsim mods will be released on my Patreon, from time to time ;)

including
  • 2016 R18
  • 2013 TS030
  • 2007-2009 997.1 RSR
  • 991.1 RSR
  • 2009 R15

I will provide new links to all the mods we had released soon.

The old cars wont be updated anymore, and dont waste your time asking me if you can modify anything or whatever, or if i can change something to your liking, these are now in my hands.


Thanks!
Thanks for picking up the baton 👍

Loaded up OK ovah heya. CSP, Pure latest.
 
Actually I did read Max's post above before I posted mine, still didn't explain what exactly happened to TomSim but good to know the WIP are gonna see light of day...
Don't worry, I was kidding, as always... My comment was because three or four pages before Max's post, the reasons for Tomsim's decision had already been explained and we had talked about it, in this post and subsequent

There is really no one who ever had this problem before?🙈
I do notice microstutters , since I don't know when

I tried everything to get rid of them, tweaked my PC to the max. (without reverting to extreme overclocking as it isn't a lack of CPU or GPU power).
I changed bios settings (disabling SMT, AMD Cool&Quiet , CCSTATE control disabled , ...)
Using process Lasso to get the game to run on single CCD every time, and have Oculus Link runtime on same CCD as acs.exe
Leaned out my Win10 (no unnesc programs or services running) and made sure my RAM running correct ,
no heat issues on RAM, CPU or GPU. Reverted to older NVIDIA driver for better DPC Latency (v566.36 was the best for me).

I've come to a point where my 4080s runs much smoother, and I get around 400 to 500fps (depending which track and grid) on single screen, and so it can handle 120fps in VR.
Yet I stick to 90fps in VR to keep some extra overhead , so I can even turn on PP filter and still keep a smooth 90fps.

BUT... still, every odd session (on average 1 in 5 I would guess) I get these microstutters and the occasional framedrops!
when it occurs I see the CPU usage in the Performance graph in AC is spiking more then usual :
1756019395119.webp

So normally it's like where the green arrow points to... but when I have a "bad" session, the normal cpu behavior only occurs a couple of times per minute , just for a second... other then that something seems to bog down the CPU constantly.
When I then restart the offline Quick Race session (no changes made whatsoever to neither settings or grid) 9 out of 10 times it's gone! Then I have a "good session" without these violent spikes and thus without stutters...

Simply restarting the session fixes it, and I eliminated so much external factors that could cause this, I'm starting to think it's something in AC or CSP which occasionally causes this (but I can't be 100% sure)... I also tried flicking several cpu related options in CSP , to no avail.

In the ingame LUA Debug app you have a memory value:
1756023557704.webp


This will rise constantly until a certain point and then it will go to a low value again. Are the stutters at the time when it lowers?

Maybe also check the other apps you use and which are running. Maybe one is bad coded and causes memory leaks and those will be removed by the LUA system, but this needs a lot of CPU power.

It is not really possible you can prevent those memory leaks in LUA, but it is possible to prevent most of them with good coding.
I see a lot of coders of CSP Lua apps, which don't have a clue of that...

Like in Pure i'm aware of this in every single code snippet and also the CPU occupation with in a frame is extra balanced in Pure so it does not cause those micro stutters.<

but it could also be caused by a background Windows process which is periodically needing more CPU power, like anti virus apps or meta data search things...

I'm interested on some of those cars. Where can I have access?

It will make no difference if you delete the PURE or SOL lines in the ext config if you don’t use SOL or Pure.

Sol or Pure are the only things that will use those entries…
Thanks a lot for your clarification, I appreciate it a lot. :bowdown:
I got the same trouble with some of the tracks brought to us by @shi , so the only thing I will have to do will be deleting the lightings.ini file, right ?

How to use this ?
You have to put the file in the main directory of the track. ;)

Thanks for your reply and explanation!
In your case, does the stutter also occur with other cars on track?
That’s the very weird thing in my situation. A lower fps but super smooth game in trackday and race weekend mode with a full grid of cars.
Proces Lasso helped me a lot and made the game running in much higher frames than before. But no bl**dy idea where these stutters come from when I’m just on my own on track 😆

@Peter Boese
when I have a normal session, I see Running Update takes up around 0.2 ms
1756035373394.webp


on a "bad" session, it takes around 1.3 ms :
1756035471598.webp

But is it cause or effect ? :) (hoping you are onto something ...)
BTW , this was taken while not using Pure and without using a PP filter...
1756035652711.webp



Thanks already for your input and your everlasting efforts!

Something entirely unrelated, ( I would like to put this in a separate post ,but that's against the rules)
How to fix the position of a floating groove?
1756030487407.webp
1756030398302.webp

would this be feasible for me to change with code in extension\ext_config.ini or would it take some work in Blender (then I can't do this myself unfortunately)
Since Bikernieki High Speed is my #1 go-to track for testing cars, I would love to see those grooves fixed (they are all floating above the tarmac now... :bowdown:

That’s me! It’s Chongs XR2. I only spent an hour or so on it when I was learning the ropes of modding AC. I could probably make it into a worthy tribute now, I just have so many ongoing projects. Namely our Sierra Sapphire Cosworth, at last a good quality 3D base!

The whole repository there is from when I was practicing, so the workflow wasn’t nailed down and some of those models would be difficult to work with for advanced modders. I got those cars into the game no matter what it took. (Decimate modifier anyone? 🤣). We plan to sift through them eventually and tidy them up!

Regardless, our mission always has and always will be to bring obscure and rare cars into AC. Some free releases often like the Vectra GSi and Rover 220 Turbo, but mostly paid mods due to the 3D’s costing an absolute bomb. No profits involved, all proceeds go back into buying more models.

If you decide to check us out on discord, just remember to head to the ‘verify’ tab to verify your email, as this will unlock all of the channels.
 
Try Max'd out. They have a MK3 Fiesta, last i knew it was unencrypted to! However might've changed since i knew, but if not the XR2i or RS Turbo factory alloys are available on Renderhub, if you're into modding.
That's right!! One of the most popular sports cars from my youth,together with the R5 Turbo and Fiat Punto GT, sadly it seems to have never been released. 😞

You put the Fiesta MK3 and the Pinto GT in the same bag as a Renault 5 turbo!
That is hilarious (to me).
