Test Patch Y24

Hello Racers.

Here is a new compatible Test Patch, Y24.

It contains important fixes for issues found in Y22 and before. Please see the list of changes below for specific Y24 information


By using the same Hardware Vertex Shading system as the car body, the subobjects (steering wheel, gearstick, brakes, mudguards, etc) now make better use of your graphics card, saving CPU time and increasing the frame rate on most computers. Those that do not experience much frame rate increase should find it is smoother and more consistent. There are small graphical improvements as a side effect of this change. You should find that the pit-out glitch is reduced as well.


Multiplayer replays now have the same interface as single player replays.
They loop and the Escape Menu is available while watching.
Also, replay controls have been added. A timeline is visible when you move the mouse.
You can click anywhere on the timeline and the replay will go back or forward to that point.

Some new keys have been added :

1) Single frame step : ',' or '.' (SHIFT + ',' or '.' = one second step)
2) SPACE to pause / unpause during a replay (same as P)
3) ESCAPE to break out of fast forwarding
4) SHIFT + F now has 3 states if you are in a replay (the 3rd state hides everything including all messages and replay controls)


User name and password are now required to go online in DEMO.
DEMO / S1 / S2 all appear in the same List of Hosts.

NOTE to DEMO users :

- You will need to set a GAME password at to go online
- Log in and click on "account details" to set your GAME password
- You will not see older demo hosts (Y to Y16) in the list of hosts
- You will see new demo hosts and demo compatible S1 / S2 hosts

NOTE to S1 users :

- You will see all S1 and S1 compatible S2 hosts in the list of hosts


- Hosts in S2 mode - no difference, compatible, all S2 users can join
- Hosts in Demo or S1 mode - all S2 users (test patch or official)
and Demo / S1 test patch users will be able to see your host
- Official patch Demo and S1 users will not see your host

DEDICATED HOST (for hosting only) : (1.5 MB)

Windows XP : East Asian Language Support / Font Installation

LFS does not support double byte characters with Windows 98 / ME. Windows XP and Vista should work well but you may need to install fonts.

If you have Windows XP and currently cannot see the East Asian translations, here's how to set up your computer so it works.
See the attachment - in Control Panel click on "Regional and Language Options" then under the "Languages" tab select "Install files for East Asian Languages".
Windows will probably ask you to get your XP CD and the fonts will be installed from it.

This is important even if you do not use Chinese, Japanese or Korean translations so you can see East Asian text and player names correctly when you are online.

Quote from Scawen :InSim : MCI packets are now sent at regular game update intervals

Could you elaborate a bit on this one ?
Nice patch, i like those gray circles on speedo and tachometers
Thanks for the new patch.
Scawen, Can I request that grey circle also on the virtual speedometer?
Quote from filur :Could you elaborate a bit on this one ?

Prevously the updates could be irregular.

As you know, each "game update" or "physics update" is 0.01 seconds (running at 100 Hz).

So in old verisons, if you set the interval to 100 ms, you would get updates every time 100 ms had elapsed. But this was checked outside the physics loop, so if your computer was running at 33 fps, for example, each frame contains approximately 3 physics updates.

So the MCI might be output with irregular intervals, like 9, 12, 9, 10, 11 etc...

In this new version, the rate set through InSim is rounded to 10 ms then the check for updates is done inside the physics loop. So the MCI packets output will all have exactly 10 physics updates between then.
Great work
Thanks for the patch

But...what happened to Y23? :S
not released. Maybe Scawen has a big surprise instead of Y23
English counting system, 19,20,21,22,24 makes sense. Its brittish humour
Wonderfull dials in the dash , more clear to see now in low end pc , like my
#15 - Byku
Scawen is a God *_*. Indeed dials... much better .
can someone post a pic of the new dials please?....I'm at the office for another hour or so
when i open the lfs.exe on Y24 it gives me that error: "could not load font"
Try to download the second link. If it's still not working read the message what scawen posted about asian font's etc.

E: shot of the new speedo.

Thanks, working fine here so far.
