Hello I have a [email protected]
8800GTX x2 SLI
2GB Ram
X-fi

After testing the game a bit I find theres no quad support and the game hits one cpu hard and leaves the others almost idle.(affinity does nothing)

Also I see no performance increase using SLi over a single card.

My question is this: Does this game support multi cores /SLI, and if not is there plans to bring this into live for speed?.


As Im getting so poor fps on the grid, and its frustrating knowing you are only using one core and one card.

I'm sorry if this subject is in the wrong place/ already a thread, I did search and found some info. but not enough.

Thanks

Unfortunately LFS uses only one core

Ouch, thats not good. Is there no plans at all to bring other threads in?, this seems to be a silly thing for the developers to have done, after all they must know their physics engine and damage model is already maxing a single core, you add more racers AI and you talking major slow down, from the cpu bottleneck.

Is there no talk of adding dual/quad support? , nightmare!.

I mean what rig can run this with lods up and 20 A.I cars, with a smooth grid, looking at other games like GTR2 etc they manage it.
I though this game would be eaten by my computer, only to find it does'nt use half of it.

When LFS was first developed multi-core processors were rare on consumer computers so support from them was not included.
There are plans to add support at some point though because multi-core processors are common now. No one knows when though, not even the developers.

What?! You dont get a decent FPS with a 3.2 GHz (!) Core 2 Quad?!

I wish LFS was multi-threaded, but with a 2.13 GHz Quad and max AA (on a GTX) i get under 30 FPS for the first 10 seconds and i'm bouncing off vSync.

Scawen said that it would take a month to make LFS multi-threaded (although i think it would be totally worth it).

LFS does "support" SLi (i didnt know a game couldn't, merely that some stuff doesn't work that well with SLi), however in a full grid the bottleneck will be your CPU, and the second the CPU load eases up you'll be bouncing off vSync.

Yeah, I didn't/don't think games support or didn't support SLI. SLI just gives you more graphical power, doesn't matter what game.

...and I don't think 2 thread were needed, 3 minutes apart.

Some games give massive FPS boosts (90% for the extra card), some actually LOOSE performance thanks to the CPU hit SLi makes.

I have VERY limited experience with SLi (a pair of 6600GT's that hardly ever worked), however i know you can get a big boost by trying different SLi modes (ie AFR and AFR2)

Like you said I think he is getting the impression that the SLI is not working because it's the CPU limiting performance first, way before it gets close to worrying the graphics cards, LFS works the CPU more, espcially with a full grid of AI's.

I'm sure multi-core support with come, but I think there are a few more important things in front of it in the list first.

from my research sli is fine depending on the cpu,motherboard,ram you buy im looking at doing an sli setup soon, have you run all the tests and told the nvidia u want to use the sli function in the n hancer?

multicore and decent sli support for LFS. I wish. real badly.

Krom, with 8x AA , and back of full grid, you SHOULD NOT get less than 50 fps, i got E6600 @ 3.0GHz and 8800GTS, at back of full grid and with 8x AA , 16X AF, i get about 54 fps. Not kidding, and with maximum ingame details too.

Quote from Jakg :

read again hes talking about the worst case situations in lfs which can get any pc to its knees and below the 30fps mark

He has TWO 8800GTXs. LFS is a DX8 game. AA is not the issue here.
