He says that not me… so it is a Pentium D and not a core duo… Even though, the cpu performance is more than enough for LFS, whatever run on start-up…



@speedpiet
I don’t know what to say you have tried everything… and since you have not performance problems with other games it is not that the problem.
It seems to be incompatibility with your hardware but I have seen pc with the almost the same configuration to work with lfs perfect… it doesn’t make any sense

Quote from Red Runner :

Hi!
The FPS-Rate is about 10-17 FPS at the start (LX6 on South City,
last place in the grid for example)
(...)
When I’m alone on the track the FPS-Rate is about 75-92 frames.
(...)
I’ve also tested to drive online (Blackwood, 8 cars on the track) the
average FPS-Rate is 75.

So the problem is only when playing against ΑΙ bots?

Have you tried updating to test patch U20?


It’s clear that there is not a performance problem… you have a Core Duo processor it is possible to capture video while playing lfs… (the cpu code must be 6xxx or else it is not core duo)

Very good video & action
Also good visual quality 1024*600 !!!
I love the color effect you added between 28sec and 34cec

With the 9700 u should have at least 80 fps…especially in the training or sp mode (online the performance drops as the number of the cars increase) I had more than 80fps (1024*768 noAA no AF) with an 9500pro…

So you have general performance problem… check if cpu or graphics card is overheated during the game.

If you don’t have any monitoring program, download from here speed fan http://www.almico.com/speedfan.php

As for the graphics card, this model don’t have monitoring system so you have to touch it to see if it is extremely hot… but expect to be hot, its expected…

Α workable temperature is around 60οC (140oF), under pressure, of course lower is better…

If you are running other recent 3d games without that instability then the problem isn’t the high temperatures…

Well if it says it is revB, you have rev B … what else do you expect to see to be convinced?

@tristancliffe
Yes indeed revving high without load damages the engine… but since engines are controlled by ECU, damage is minimized.
That’s because when you reach the rev limit that manufacturer has set, ECU cuts ignition and/or fuel injection periodically so to keep the energy which is produced by gases in safe limits for the crankshaft.

Fortunately all manufacturers are preservative when setting rev limits for the every day driven cars they make... That allows «boy racers» to rev the engine always-anytime on the rev limit and stil not braking the crancshaft, only cause more wear...

Quote from masternick :

i have lots of DVD's with jap drag racing and lots of the racers there use the rev limiter to tell them when to shift it's fun to bounce off the limiter

It’s fun but it slows you down because when you hit on the rev limiter the power oughtput is also limited.

Don’t confuse normal rev limiters with launch control systems.
Also when starting an fwd car, due to the excessive wheelspin, first gear is kept (while engine runs constantly in a rev limiter) till you reach the wanted speed so when second gear is selected, the revs will be within the power band.

There is not Japanese drag racing or any other country’s drag racing… it is just drag racing and is pointless to give examples from that because drag engines can stand only few passes on the dragstrip…

Yes indeed

Too much power wasted just to move nonchalently all that mass… Its like not racing at all… seems to be like a destruction derby…

600W psu isn’t small…
Simply it was defective… or totally crap…

Here is a review of Logitech G25 racing wheel.

http://www.hardware.info/en-US ... G25_racing_wheel__Review/

It’s good to see the details and there is a video showing a guy driving with it…

Disappointingly, as it is shown on the video, he is reviewing an 900degree wheel in 200 mode OMG useless reviewer!!!illepall

Training… You can see that after a few completed laps they get faster. But there is a limit… though I don’t know in how many laps they reach their limit, I think they are not competitive at all...

If you can beat a well trained pro AI, you are ready to start racing on line, being 5 or more sec slower than the average racer.

This thread suits better at the LFS Beginners Forum and with the help of Search button you could find many threads related to ΑΙ competitiveness.

You can’t adjust all that parameters in a usual road going car as it comes from the factory…
Off course you can have some restricted adjustments, it in some cases, with several aftermarket parts
It is also easy to reprogram or put an aftermarket ecu ... and tune it to rev in higher rpm.

But if you put aftermarket parts… that is no more a normal car…

LFS cars are not normal… they are all race prepared.
So it is not strange that lfs cars rev to high

@Jamexing We don’t disagree I am just explaining what I am saying…

Honda s2000 99 - 03 engines where 2L producing 240ps @ 8300 rpm
And they appeared in 90s civic , crx with an 1.6L engine producing 160ps ,185ps (type r) revving at 9000+ rpm

None of the lfs cars are usual road every day driven cars…

In no usual road going car you can tune all that suspension, steering, braking, and camber characteristics… not even with an aftermarket suspension system… there must be a lot of custom work to adjust all these… and if we are able to do this why not having a race tuned engine?

Mine dfp does that too…
But the noise which is produced is not so intense as u describe

I checked inside and i found that the main motors cogwheel is not very well center to the motors axis.. it’s a little bit cam. its about 1/10 or less of a mm off.

You should take a look inside. and see if it needs some grease . ( use grease proper for plastic moving parts )

Quote from wheel4hummer :

Hey, at least I didn't say "Power = torque x rpm"

I tried to keep it simple just to support the above what I was saying about xfg..

Bit I forgot the unites used in lfs and from country to country…

With kgr and watts it just works and it just a Simple “version” of the original Power = Torque x Angular Velocity.

But it was my mistake after all.

Quote from sinbad :

I have always thought that most of the cars are a bit too willing to rev way above their peak power, but it doesn't really bother me, I always shift at the light.

Exactly that!

Mmmm... Pie!

3.14159....

Quote from Shotglass :

for crying out loud use proper units !

When calculating I use SI system…

Torque measured in kgm and power in W

@S14 DRIFT

Is that a joke?
Apart from the wrong measure unit…

An engine can give max torque in a certain rev band which is determined by intake-valve train- cylinder head - and exhaust system…

At 5000rpm your Rav4 engine produces much lesser torque… but even if it was possible to keep up το 185ft/lbs (25.5 kgm) at 5000rpm.. the extracted power would be around 127KW or 170ps…

All race cars are more free-revy than the every day driven normal cars.
Τhat’s because we need as much power oughtput we can, from an engine which doesn’t need to last for as mush kilometers as in usual road going car…

All rpm power bands and rev limits are absolutely realistic….

Someone mentioned xfg rev limit… the smaller the engine is the easier it can rev in high rpm (don’t start about geometric characteristics or valve train springs… i am speaking generally…)

And how you expect to extract 115ps from a 1.3L engine? You have to make the engine rev at high rpm…


As for the RX es engines…wankel is much different from the piston engines and lfs doesn’t have rotary engines… so there is not a point to mention them…

I think that power curves are not so realistic… And that makes gear changes not to matter a lot…

Man! Just read the post above!

This is a known dfp problem… it hasn’t happened to me yet so I don’t know the solution, and i am not going to search it for you.

Here is a site with useful repair tips… the problem seems to be somewhere else.

http://web.axelero.hu/mozso/momo_e6.html

The site is for Logitech MOMO Racing, but the mechanism is similar to driving force pro

I think it is that… And I have broken the sensor which sees it…
The strange thing is that the wheel still calibrates perfectly itself.
You just must not touch the wheel while it is auto calibrating because it take as center wherever you move it.

It is very good!!! When it finished I wanted more!!!
I really do not care about the scenery, although it is perfect racing in it.

These are my favorite and i think that they are classic.

Ahem … that was it.. i just didn’t know which driver to choose from the list.. There were a lot containing (acpi)…. But I had just to pick exactly that “power interface (acpi) pc”…
