Induced understeer works GTR2

At least one noticable change in the physcis between GTR and GTR2. When slowing (lift throttle) or braking, and the rear end steps out, you can steer inwards to cause the front end to plow, to correct the oversteer (driver induced understeer). This rarely worked in GTR, but it works well in GTR2. For acceleration, normal counter-steering (outwards) and throttle modulation are still required. For some real racing cars that don't have downforce, when cornering at very high speeds that require full throttle to maintain speed, a bit of induced understeer can help stabelize a nervous car. Some players did this with Grand Prix Legends.

I think the effect was a little overdone in GPL.

Seems to me the physics in GTR2 are greatly improved over the first version in general. Racing in the rain is really cool , they did a very effective job with the sound of the rain,thunder,and the physics of driving on wet pavement. To me it is the rain thing in GTR2 is the most amazing achievement of any sim ever and I have tried them all. Steve P

Not as much as an F1 car but several have better downforce:drag ratios (thanks to the fenders). , when cornering at very high > speeds that require full throttle to maintain speed, a bit of induced understeer > can help stabelize a nervous car.

>> (driver induced understeer). > I think the effect was a little overdone in GPL. The cars in GPL, 1967 F1 race cars, rearward weight bias, no downforce, high working slip angle, are probably ideal for using induced understeer. I've read that the Lotus team manager heard Jim Clark describe using induced understeer, with the manager responding, that's why he's a manager and not a driver. I've asked some club level race drivers about using induced understeer, and although it's not needed on most cars, there are a few where it's used. One guys comment is that his Clio was evil, and he had to use induced understeer, to keep the car in check on high speed turns as I mentioned. Most guys that get to run their cars on ovals for fun end up getting large rear wings to keep their heart rates in check. GPL did have a induced understeer quirk, on the Lotus, if braking balance was around 53%, you could get a reverse steering yaw reaction when braking hard. Also using front toe out could be used to keep a car stable under heavy braking. I made a video of the reverse steering reaction, although the video only shows a left yaw, I could steer left and get a right yaw on the same section of track: http://jeffareid.net/gpl/gplrs.wmv The worst "offender" of induced understeer was with LFS S1 all or nothing grip factor, especially on the LX6: http://jeffareid.net/lfs/lx6.wmv Induced understeer used properly (just a bit) and coutner-steering, Rouen by Greg Stewart. Tires inwards while slowing, outwards while accelerating, inwards on the very high speed right sweeper. After the 90 degree left haipin, the next two acceleration right turns are done with the steering spending most of the time left (throttle oversteer). The bottom (chase) view of this video give you a good idea of what is going on. http://jeffareid.net/gpl/gplrngs.wmv

How big is the effect on FPS during wet weather racing? cheers, uwe -- GPG Fingerprint: 2E 13 20 22 9A 3F 63 7F 67 6F E9 B1 A8 36 A4 61

Very little on my system. At 1280X1024 I get a 4-5fps hit in rain with most video at high or max levels. 3.6ghz EM64T Intel and ATI X850 PCIE graphics. All in all GTR2 is about as demanding as GTL on my system. I always get this stuttering when pulling out of the garage in GTR, GTR2 and GTL.......... Other than that all is, for the most part, very smooth. Ed

OVERCLOCK IT!! Hahaha. Is your X850 pro or XT or regular? Mine is AGP so I was able to unlock the 4 extra pipelines so now I have 16. :)

Did that. Running mem @ 620, GPU clock @ 540 and very stable. Mine is the X850 PE already at 16. Ed

FYI something bad wrong in vid? Jeff Reid enlightened us with: >>> (driver induced understeer). SNIP>>> > car stable under heavy braking.

I cant play it, jerky as hell, takes 100% processor time, dang near locks the whole system (yeah your right is is probably SSDD Microsoft..) checking now if all new ones are this way, but I had viewed a lot of your older wmv & mpegs you ve posted... hoping it is not just me... lol Nope, just the GPLRS.WMV I cant play... Next 2 played fine though... > The worst "offender" of induced understeer was with LFS S1 all or > nothing grip factor, especially on the LX6: > > http://jeffareid.net/lfs/lx6.wmv

Lately they've been doing more maintainance on the building where my web site is hostes (ipower), so the download rate may vary. Most of the time it's very fast, I get about 1.4 mega- bytes / seconds on a 12mpbs cable modem.

Good stuff. :) I am waiting for my 3M pads to get here before OCing. Ed Medlin wrote:
