I'm currently finalizing an all-in-one patch for Total Immersion Racing that should do for TIR what the "Advanced Physics Patch" did for SCGT -- I've solved the brake lockup problem, and the modifications that I've made to the grip levels and tyre sounds completely transform the game. If you're looking for something new with a rewarding physics model, or if you've been searching for a new sportscar sim, then TIR with my advanced patch just might be the ticket. Some of the tweaks have been posted on the High Gear TIR forum previously, and some are of my own making. Ultimately, my patch will make for an all-in-one method for everybody to obtain optimized, standardized physics settings. That will open things up for offline leagues and hotlap competitions and such, which should help further spur some interest in the game.

The issue of brake lockup (or lack thereof) in TIR was solved by modifying the tyre sounds -- brake lockup DOES occur in the game, but it's undetectable. The chicanes at Monza were absolutely frustrating for me -- I "know" the new version of Monza fairly well, and I can handle the chicanes well in other sims, but in TIR all I would get is a terminal snap-spin or a slide-off into the barricades. I KNEW the reason this was happening was because I was unable to detect the onset of brake lockup, so I started dissecting the various sound files and sound levels in the .dat files, and I finally came up with a group of settings and tweaks that provide excellent audible feedback regarding your grip.

With my sound and physics modifications, I can now detect how much drift or how much steering input I have dialed in via the tyre sounds, and terminal brake lockup is a thing of the past. To verify that I haven't just "learned the track," I have now unlocked ALL the tracks using the cheat, and I can go to ANY track that I haven't driven before and make my way around at fairly competitive speeds without any unexpected snap-spins or slideoffs. The feedback is now dramatically improved, and the addition of audible tyre sounds and brake lockup noise has enabled me to tweak the magic grip levels -- without the tyre sound tweaks, the tweaked magic grip levels were almost impossible to use (for me anyway), but with my new sound tweaks, the new magic grip levels feel, well, magic. If you like hardcore sims and you appreciate GPL or F1 2002, you may find that my new tweaks reveal the TIR physics model to be VERY sophisticated indeed.

My patch will work with the demo version as well if you'd like to sample the goods in advance. The demo only features a one-lap race, though, and since TIR also models tyre and brake temps (it feels a lot like a Papy or MGI sim in this respect), you really need to put in a couple of laps to warm the tyres up before the physics model truly "comes alive." There is a way to access more laps in the demo, so if you'd be interested in trying out the patch with the demo once I have it ready for release, drop me a line.

Also, FWIW, if you're a fan of Live For Speed (LFS), you might be interested to know that Scawen Roberts (one of the LFS developers) is credited as a physics consultant in the Total Immersion Racing manual -- with the physics and tyre noise tweaks that I've come up with, TIR feels a LOT like LFS, physics-wise (but with higher performance cars), which ain't a bad thing!

Stay tuned -- TIR is about to get REALLY interesting!

Sounds great John....can't wait.Still haven't been able to find the full game around these parts though.

I did run a 25 lap race at Monza the other night and certainly noticed the tire wear in the physics.Saw my lap times drop by 3.5 secs a lap and really had to adjust my braking points etc.

Wait until you see what it's like when you can actually detect brake lockup!

You wanna be my beta test guinea pig for the demo version, Splash? Drop me an e-mail if you can -- I don't have your current e-mail address, I don't believe.
