Happy New Track DUNDROD 1950 Released
Well, almost new
Dundrod 1950 Circuit
COPYRIGHT
This Dundrod50 track is released for the personal use of my friends in the GPL community, in GPL.
All original work in this release, including track file, altitude data, track centreline, track 3do and original textures, is copyright Jim Pearson September 2004 and June 2006. All rights reserved.
This is not a Papyrus product. Use at your own risk.
These files are not to be copied, used in full or in part for any commercial purpose, converted to other simulations, or mirrored on other sites without my specific written permission.
This track is my attempt at an accurate recreation of what Dundrod is really like to drive AND look at on a partially cloudy day. The horizon is the real one, [ courtesy of PhilJ photos ] and the groove is intentionally broard and light, because long narrow road tracks never 'mark up' like short circuits. So please, refrain from producing revised groove mips, CLN and regroove files.
If you think the textures can be improved, please consider the overall harmony that I have tried to create and pay me the courtesy of showing me any add ons for GPL before you release them.
DUNDROD, NORTHERN IRELAND - 1950 to 1964 Circuit
11.93 km of public country roads west of Belfast, closed for race meetings. Narrow, bumpy, blind apexes, sudden dips and drop offs, roadside ditches. Very fast and very dangerous.
A circuit which hosted several rounds of the World Long Distance Sports Car Championship and the British TT in the 1950's, with works entries from Jaguar, Aston Martin, Maserati, Mercedes, Porsche and M.G.
Stirling Moss won the 1955 race in a Mercedes 300SLR from Juan Fangio in another Mercedes and Mike Hawthorn's Jaguar D Type. However tragedy struck during that race with two separate fatal accidents at Deers Leap and Cochranstown, in which three drivers died. Road racing in sports cars was subsequently abandoned at Dundrod, but the bikes and sidecars continued to race and still do so twice a year in the Ulster Grand Prix and Dundrod 150.
CIRCUIT DIFFERENCES
The first GPL Dundrod I released in 2004 is a representation of the public road circuit used for bike racing from 1965 onwards. I released that first because that was the circuit in use during the era of 1960's GP racing on which GPL is based. However F1 cars never raced here.
This Dundrod 1950 circuit is the circuit used between 1950 and 1964. [ 1950 to 1955 for long distance sports car racing ]
It differs at Leathemstown [ the old road into the valley to the RHS was in use then ] and at the Hairpin [ the track went right down to the road junction in those days; the shortcut through to the lower/return road further up the hill not being used until 1965] .
I have included these changes, but also taken the opportunity to refine the driving surfaces and track routing in many other places.
My Dundrod "green" textures are used as a base, but I have lightened/ refined many of them further and changed some of the object mapping and choices.
This should provide a more realistic and accurate racing/driving experience, as well as differentiating the tracks somewhat.
ACKNOWLEDGEMENTS
I wish to again thank my three original testers from the Racesim Central forum;
Ken Murray, who has raced bikes at Dundrod and knows the risks inherent in the real track all too well - see memorial plaque at Ireland's bend.
Phil J, a local resident who has driven many private 'laps' here in real life; and
DDangermouse.
Thanks also to PhilJ and John Black in particular for providing valuable archive and current images as reference material.
Special thanks to Paul Jackson and SPEEDGEEZERS plus DD and the Mirror Zone for blind hosting the downloads/mirrors and lastly;
The many clever and generous people like Phil Flack, to name just one, who made the excellent track making tools used to produce this work. The shadows in the first Dundrod were made mainly by manipulating the groove file, however Phil's snappy little vertex shader has been used to replace them in this version.
A FEW QUICK NOTES THAT SHOULD BE WORTH YOUR WHILE READING, PERHAPS WHILE YOU ARE DOWNLOADING
1] SHARP OPEN GL TEXTURES
There are no specially mapped Open GL textures to sharpen up roadside/asphalt for this version of Dundrod. I have realised that this is unnessesary, because turning on AF [ Anisotropic Filtering ] in your video card settings will achieve better results. 4X, or better still, 8X or 16X AF will make this track, or most others look as sharp in Open GL as they do in D3d.
You can also use at your own risk, desktop tuners like "aTuner" to do this.
The reason D3d is always sharp in GPL is that the D3D Rasturiser in GPL has an inbuilt AF setting, usually set to 8x or 16x. The Open GL Rasturiser [ original one at least] does not have this feature, so you need to set this manually as above if using Open GL.
2] HOW TO APPROACH DRIVING IT?
Four tips from me....
a) DONT BE CONCERNED BY TRACK WIDTH - It looks very narrow to start with, and the bumps and roadside ditches/field drop aways are a little unsettling if you have been driving wide 'billiard table smooth' tracks, but learn the few tricky corners, DRIVE SMOOTHLY and you will find there really is a lot of room. GPL tends to make tracks look narrower than they actually are to drive.
b) BRAKE EARLY, never using more than 2/3rds brake pedal, especially in the three bumpy downhill braking areas; and
c) TURN IN EARLY toward the apex of all the medium to fast corners.
d) Drive on front wheel feel/grip going into corners and rear wheel feel/grip coming out.
ABOVE ALL, THIS IS A TRACK THAT REQUIRES VERY PRECISE STEERING AND USE OF ALL THE AVAILBLE ROAD WIDTH.
DONT JUST FLING IT AROUND AND EXPECT TO STAY ON THE ROAD. CONCENTRATE AND YOU WILL STILL BE ABLE TO DO DELICIOUS LONG DRIFTS THROUGH THE MANY MEDIUM/FAST TURNS HERE.
BE DISCIPLINED AND YOU WILL DO OK AND ENJOY THE CHALLENGE, but watch out for those roadside ditches!
3] SETUPS
There are some setups of mine on the Dundrod Downloads page for both 67 and 65 sets of chassis. Suitable for both Dundrod versions. Additionally, the 67 default setups are mine. The included Replay lap was done using my Default Brabham BT24 setup.
If you are having trouble controlling the car at corner entry/under heavy braking, try making your front Shock "bump" settings and wheel rates a bit firmer. This should improve braking /entry line stability without much if any effect on grip.
4] SHRUBBERY
There are selected [not all by any means] places in the shrubbery where you can drive straight through it. Usually in spots where you could hit it fast and almost head on, like outbraking yourself into Quarterlands for example.
Why did I make it like this?
I had a choice. The traditional 2055 collision value for hay which makes a car stop abruptly and invariably traps it if hit at that big angle. The alternative was to remove the collision and allow the car to drive through into the field beyond then return the same way, only penalty being time lost.
In reality what happens when a 1000lb car plus driver hits a small roadside hedge or flimsy two strand wire fence head on at even 50mph? It goes straight through it.
So I maintain that removing the collision in these spots is closer to reality than leaving it in, having the car come to an abrupt stop, then become trapped, with Shift.R the only way to release it !
5] HOW DO YOU PRONOUNCE DUNDROD?
DunDROD....... with much greater emphasis on the second syllable.
Thanks for reading this. I hope you can now enjoy some 'Almost Real Road Racing' on this classic Northern Irish Circuit.
