I don't think its overclocked E7600 @ 3.06 GHz I think thats stock.

Thats correct.

Quote from SparkyDave :

Juozas, is your LFS standard or have you updated/installed any 3rd party mods or texture packs?

Reinstalled to empty folder as first measure, did not help.

Quote from SparkyDave :

Have you tried switching AA + AF off ingame and setting in global 3D settings CCC or similar?

Just tried, did not help.

Quote from SparkyDave :

If you can install another OS on second HDD even just to use for testing it might be usefull.

Still thinking about it, guess will do it for testing.

Asus Qfan and AI suite have given me probs in the past, I would disable any Cool&Quiet stuff in bios on a gaming PC I like to have full speed CPU all the time.

AI Suite only installed later, when wanted to check current CPU clock. Tried to disable Cool&Quiet in BIOS, but did not help.

Here are a couple of other threads with similar/same issues, some have been fixed with new clean LFS installs.

Could be onboard sound card problem, but do not have external sound card for testing at the moment. BTW installing newest Realtek drivers did not help.

Thanks.

Quote from cargame.nl :

Updated sound drivers to newest version?

No. Using newest microsoft drivers. Maybe will try to install newest realtek drivers.

Quote from SparkyDave :

From your video posted, it looks to me like the freeze occurs when you get closer to other cars, and the LOD increases at this point. do you use the "multiplayer speed up" option in LFS/Options/misc ?

Yes, I use "multiplayer speed up". Tried to change distance and Dynamic LOD reduction, but frozing still happened just before car showed up.

Quote from SparkyDave :

watched it again and this defo looks like a GFX driver glitch as the detail goes up so trying an older gfx driver (and older DirectX) could fix your problem.

I doubt, I can install older DirectX version on Windows 7, it comes with v11 preloaded. Maybe will try installing XP on second drive...

Quote from SparkyDave :

Are you using the ATI CCC ? is so uninstalling and using something like traytools might be a better option for you.

Had CCC installed while updating GFX drivers, but uninstalled later, because it got unstable after installing Asus AI Suite.

Quote from SparkyDave :

Does this only happen online? try racing with a full grid of AI drivers(with non default skins) and see if you still get the freezes.

Tried to race offline, before start I tried to loock behind and got same freezing, when racing, it does not freez until you or someone form AI gets damaged, its enough to only slightly touch another car and freezing happens.

Thanks.

So I managed to somehow reduce LFS freezing by disabling CPU clock throttling (disabled C1E and Extended Throttling in BIOS), but still I experiance some freezing while e.g. driving through pits while there are several cars pitting.

Hi, so I tryed LFS demo and while playing online it keeps freezing for a fraction of a second when other cars enters my "field of view" i.e. when car gets rendered for first time, as it gets closer to me. Freezing happens also when my, or any other car in my "field of view" crashes, or gets damaged somehow.
When this freezing happens, screen is not rerendered at all, after it, LFS shows some random FPS number, and when again returns back to FPS limiter, e.g. fps goes like this: 100, 100, screen freezes for half of a second, 22, 100, 100.

My system:
CPU: Intel Core 2 Duo E7600 @ 3.06GHz
GPU: ATI Radeon HD 4830 512MB
OS: Windows 7 x64

Updated GPU drivers - no effect.
Selected minimum graphics settings in LFS - no effect.
Tryed to change almost every setting in LFS - no effect.

I did a video capture of a problem I have. You can clearly see LFS freezing: LFS freezing
