This is where it is soo much different for me as I am actually leaning and moving my head as if on a real bike.

I was more talking about turning than tilting your head.

Have you tried FaceTrackNoIR DD?  (it includes freetrack plugin for use it with IR leds)  Works quite well with GPB.  I'm not using it though, because im using my phone camera as webcam with DroidCamApp , and you get some lag with this method.
But should work well with a good webcam

I wouldn't bother to use led tracking device or phones:  just buy an EDTracker. It's cheap and works much better than IR or led trackers (http://www.edtracker.co.uk/).

Did a few nice laps with Warlock on the Varese at Aragon.
First you see some unwanted stability for a change and then a weird engine seizure just after getting on the brake from full throttle in third gear.
I did not even have time to engage the clutch for a downshift. The rear wheel locked right away.
Does GPB have random engine seizures?
Killing a two stroke by 'overreving' should really not be possible (in realistic scenarios) because the gas dynamics act as it's own rev-limiter.

BTW, how can I increase the replay buffer?

Killing a 2 stroke engine due to over-revving was definitely possible(and also very likely to break the engine if you continually went into the high red RPM range) and was something a rider had to be aware of in the old school days to not continually over-rev a 2 stroke engine.  ;)

At the end of your gpbikes.ini add this

[CORE]
replay=500


or more if you want more (remember the B8 entry is now in Mb unlike before so don't enter crazy high figures.  But beware! If you go too high (dependant on your system) some tracks will just core.exe when loading. If this happens reduce the replay length until you get your stability back. There is a clue to the core crash/memory allocation/memory wipe between loading events problems here I'm sure....

Absolutely agree!!

It is much easier to blow a 2-stroke engine than a 4st! Many people have no idea of how fine tuned the 2st race bikes really need to be to run perfect and still on the limit where you don't just blow it, takes ages of experience! Having raced quite well trimmed 125GP bikes with ex-world championship parts, i have been there and i can't count how many times the engine have stopped, normally it would be the piston, but have tried much worse too. Getting the 2st to run well can be a pain in the arse!

So i wouldn't say it is weird in this game, we do rev the bike quite high and don't really go carefully with over-revving the bikes

2st can die quick bro. I blew the S80 motor in 1 lap just downshifting wrong.

In real life that Castrol are is the blood of a 2st. Only time I blew a 4st so quick was when I was young(haha) and we ran a Honda C50 on JP5.............oh shit it was quick..........for all of 30secs then melted the piston!!!!!

You have to be aware of the 2st also not having so much back pressure which slows the piston down on a 4st, not on the 2st and you can very easily over rev to often without realizing.

You probably melted the whole engine in that corner at full revs  ;D lol

Great fun last night by the way  ;)

I thought it was only a concern on the ridiculous engines like the 125s and 250s, not the 500s.
But good to have Meyer here :D


And thanks for the replay thing, Nick!

Man, how great it would be if the replay lag would be gone.
Also, an option to focus the track camera on a group of bikes would be nice for watching races.

No worries. I did a camera from helicopter view once for Mallory so you could see all the little bikes going round the whole circuit haha. Nice to see everyones position. But a long way away hehe.

Yeah I've asked about this in the past too. Having a camera that you can set with multiple riders close together if they are 0.xxx seconds from each other the camera should zoom out and keep them all in shot. If the gap gets bigger it showed zoom back in to normal.

Wait, since when does the engine not bounce off the limiter anymore?
It's not possible to tell by ear anymore...

The two stroke engines didn't have RPM limiters.

Though I believe one of the last 250 2 stroke racing bikes did dabble with some-kind of RPM limiter system not long before they were dropped from racing for the 4 stroke.

Vini

It's unrealistic but if I remember correctly the 500s had a limiter in GPB.

But more importantly, the sound is gone for the four-strokes. When was this changed?

Unrealistic? Sorry Vin but that was reality. 2 strokes didn't have RPM limiters.

Yes, and incorrectly so, the 500 in GPB did have a limiter in previous betas.

What's up mate? Do you keep blowing the 500 engine now? Lol  ;D
