go to the cfg. file in your lfs folder and find the

FF Steps 128 and change that to 256 and see how you like it....

What does that do?

Quote from deggis :

No, don't try them. Just stay with your previous ("100-0-0") settings. They are even recommended by Scawen himself.

Those settings are recommended by Scawen for the Logitech Momo black?

That's 100% overall, 0% spring, 0% damper? And what with the centering spring?

What are your FFB settings in the Windows Control Panel > Game Controllers?

There are four:

Overall Effects Strength
Spring Effect Strength
Damper Effect Strength
Centering Spring Strength

I have the same wheel and use 50% overall, 150% spring, 150% damper. Centering spring is disabled. I got lots of feedback on curbs, bumps, etc. so I think you have something configured incorrectly.

I'm forced to go with AS Club, but I've been having quite a lot of fun on SO Sprint 1 on Redline #1 lately. It's a blast when others actually use their brains and brakes into T1.

It was indeed my drivers. Before when alone I started at 43 FPS, now I get 95. With 10 AI cars I got 9-16 FPS at the race start, now I get 45-50. An enormous difference.

Thanks a lot for the help everyone, and especially DEVIL 007 for reminding me about the possible driver issue.

P.S. As a small side question in order to avoid creating a new thread, what does the "Simple Track" option do? I have it set to "Off" currently. When I try either of the other settings, it absolutely murders my framerate. Last time I tried it my FPS went from 60+ to 5.

I tried clocking my CPU back to stock speeds last night as well. I lost 3-4 FPS.

I haven't tried rolling back to the 5.11s (I'm using 5.12s now), I guess I'll try that and see what happens.

Quote from DEVIL 007 :

Hi,
I am just curious how you can be sure its not throtling?

I use ThrottleWatch. It only throttles when the temp gets into the high 70s. The 60s is high, but this chip runs very hot. Besides, why would it throttle in this game only, and not all my others? My other games run great and have no such issues.

You say you get 40-70FPS, is that alone or with other cars? Online or offline? If it is offline alone, then you're getting better FPS than me, which is ridiculous considering that the X800XL is quite a bit more powerful than the 9800XT.

Quote from DEVIL 007 :

Hi,
Can you check what temps have your CPu while playing LFS?

I see your CPU is overcloked and P4 processor are very well know that that have some protection future which insert internally empty cycles when CPU overheat which mean that at this time processor do nothing which reduce heat.

Could you try as well to downclock to default CPE speed and then check what FPS you get?

My overclock was done very carefully. I'm using a good cooler with Arctic Silver 5 and have my case fans placed so that they cool with maximum effectiveness. My idle temp is ~42C and load is ~63C. Absolute max after an hour of play is ~66C.

I know about my CPU's heat protection features and I know that it is not throttling itself.

I will try adding 10 AI cars now, just a minute.

EDIT: With 10 AI cars plus myself on AS Cadet, my FPS at the start was 11. I watched it for the first half-lap and it varied between 9 and 16. When I turned off the track and faced away from the AI cars, my FPS shot up to 40+. This leads me to believe that the rendering of other cars is what is causing the FPS dropoff, not the physics / AI thought calculations. Although I could very well be wrong. This doesn't explain why I have low FPS when alone though, assuming it is in fact abnormally low.

Hello,

My FPS in LFS is lower than I expected. When hotlapping alone on AS Cadet, my FPS varies from 43-59. This seems low considering I read on another thread that someone with a 9800 Pro got 100+ while driving alone.

Strangely, reducing details, reducing resolution / AA / AF / textures / mipmapping outside the game have very little effect on my FPS. I tried dropping the res from 1280x1024 to 1024x768, turning AA and AF completely off and reducing in-game settings, but I still get pretty much the same FPS. This leads me to believe I have some option set incorrectly which is limiting performance.

Online race starts are my biggest problem; my FPS often drops to 10-15 during these.

Here's my system specs:

MSI 865PE Neo2-PFISR motherboard (BIOS ver. 3.8)
Intel Pentium 4 2.8e @ 3.5GHz
Thermaltake Spark 7+ Xaser Edition CPU HS/F
2x512MB OCZ PC3700 Gold Edition Rev 3 Dual Channel Enhanced Latency DDR466 @ 500MHz (2.5-3-3-5)
Gigabyte Radeon X800XL AGP8x 256MB VIVO
Creative SoundBlaster Audigy2 ZS Platinum
Maxtor 6Y120M0 120GB HDD 7200RPM/8MB SATA
Seagate ST3200826AS 200GB HDD 7200RPM/8MB SATA NCQ
Sony DDU1612 40x/16x DVD-ROM
Sony CRX230ED 52x/32x CD-RW
Enermax Noisetaker EG475P 470W PSU(+3.3V = 34A, +5V = 40A, +12V = 33A)
Ultra Dragon ATX Mid-Tower Case
Windows XP Pro SP2

And my relevant in-game settings are as follows:

1280x1024x32 @ 75Hz
User LoD: 0.90
Dust LoD: 0.40
Mirror LoD: 0.10
Screen Width Affects LoD: No
Track LoD Reduction: Yes
Mip Bias: -1.00
Shadow Type: Low Res
Simple Wheels: Off
Disable Trees: Mirror
Disable Flags: Mirror
Disable Rubber: Mirror
Enable Dither: Yes
Enable Mip Filter: Yes
Use Compressed Skins: No
Half Texture Size: No

Hardware Vertex Shading: On
Z-Buffer Depth: 24
Simple Track: Off
Haze Effect: Yes

My settings in Display Properties:

2x AA
Quality With Trilinear
2x AF
Texture Preference: High Quality
Mipmap Detail Level: Quality
V-Sync: Always Off

I'm using ATI Tray Tools, and have the following tweaks enabled:

Support DXT Texture Formats
Support Bump Mapping
Support AA Optimization
Support AF Optimization

Alternate Pixel Center is disabled.
Temporal AA is disabled.
Catalyst AI is High.
Texture LOD Adjustment is set at 0.

If I am missing relevant settings, let me know and I will add them.

If anyone sees any settings that are obviously incorrect, let me know why they're wrong and what I should set them to.

I have read the manual, but it is old and outdated. Many of the settings it talks about no longer exist. The LFSWiki page is down and has been since I started playing this game.

Thanks in advance for any help.
