Isle of Man TT Circuit For AC: Tackle The Mountain Course On Four Wheels

Radical Rear end IOM.jpg
The Isle of Man Tourist Trophy holds its 103rd running this weekend - and its infamous 60-kilometer Mountain Course for Assetto Corsa has received a timely update ahead of the event.

It is known as one of the most dangerous races in the world: The Isle of Man Tourist Trophy sees motorbikes fly around public roads on the namesake island at ludicrous speeds, with riders' heads often missing lamp posts, walls and other obstacles by mere centimeters. In total, 266 competitors have died at the course since 1911 - danger lurks at every corner.

Bike racing fans have the dedicated TT Isle of Man: Ride on the Edge series of games to tackle the 60-kilometer road course that leads them across most of the Isle of Man. However, it is also possible to run the Mountain Circuit on four wheels - thanks to Assetto Corsa mods.


Created by mod author Frank1463, this hard-to-tame beast of a track has been available in AC for almost seven years as of May 2024. However, with a major graphical overhaul now completed by OverTake user ImWilde, you can now race at the legendary road course with all of the graphical pleasures that modern modded Assetto Corsa has to offer.

Road Surface & Scenery​

Whilst not a part of the new update, the road surface of the original is still very detailed - especially if you like to mess around with the photo mode within Assetto Corsa. The ability to catch cars bottoming out on the bumps of the unrestricted roads of the IOM is something very special that is very hard to find, even in a title with a modding base as wide as Assetto Corsa.

Radical SR3 XXR's screaming around the IOM TT Circuit.

The notable changes to the already fantastic IOM TT circuit's scenery include an overhaul of textures and the addition of rainfx, treefx and grassfx. These updates might sound small, but when they come together, they transform the surroundings of the track.

The best example to give is the quality of the overhanging trees. The leaf textures make it hard to see where you are going, further adding to the dangerous nature of racing on the closed public roads of the IOM. Extra buildings, objects and road signs have also been placed although they are not always true to life.

New buildings and road signs are part of the update.

Further updates are planned for the graphical roadmap of this awe-inspiring circuit. Assetto Corsa is full of cars to choose from, like the Radical SR3 and classic F1 and open-wheel cars feel unbelievable shooting through the narrow roads and across roundabouts and junctions.

But it would not be AC modding if there were no motorcycles available for what is a title that was never intended to support them. @jurik1984 has created a sidecar motorcycle mod for the IMZ M63S Strela-1 that should feel right at home on the Isle of Man Mountain Circuit - do let us know how you get on should you decide to try these bikes!

I did the same yesterday, and agree, how Connor can promote this and ignore the rF2 one is beyond me especially since he's a photographer.
It's got to be down to AC bias.
@Connor Minniss please try the other version then update the article.

I can assure you I have no AC bias... I was unaware of the RF2 mod and will certainly look into the mod for a potential future article :)

It’s quite a story, from the days of GPL and 14 years dedicated work by one man then a brilliant conversion something the creator had never allowed before. Once you've tried it you'll maybe understand why I'm so annoyed at the neglect.
BTW while you're there check out his amazing Dundrod, also rF2 conversion.
If I didn't already have it I'd buy rF2 just for those circuits.
 
Thank you, I did not know about that mod, you made me curious, I went to the workshop, installed it. Not impressed, but glad I could try it.

Looking at your picture, you need to work on your version of AC, mine looks nothing like your and looks very 2024.

"Need to work on my AC"..?

Apart from my AC and CSP being pretty much maxxed, what else would you recommend, sir?

If you look at the picture in the OP

You an see the trees looks nothing like the one in your picture. Same in my version of AC.
Without knowing what your setting are, how would I know what you should do?
My point is just that it can be much better than what you seem to be getting and was complaining about, but you probably already know that. :)

Do you honestly think I haven't seen the screenshots in the article, or are simply in this thread to troll?

I won't ask your age, but I started working/fixing computers sometime in '95, and simracing about the same time.

Regarding the tree texture, the screenshot you posted (from the article) is from somewhere on the track. The screenshot I posted is from the pits. The fence textures here were state of the art in 1998 (shot from the article too):

Then again, someone else in this thread tried the mod and confirmed the same thing (right after your post): that it looks bad, to put it nicely.

FIY, this is how AC looks on my side when the track isn't shite:

Is it possible you have a different version than the download linked in the article.
No one could accuse me of being that fussed about graphics neither do I want to denigrate the work of the AC modder but I felt the difference was significant both in accuracy and looks.
The best version I've came across is for sure Ride on the Edge and the closest to that is Jim Pearson's imo.

I think the problem is that in most weather conditions those TreeFX trees look like crap on almost every track that uses them. This is not an exception.

This version of the track can look very nice, but you need some time to find a correct time/weather combination for that.
