Suggested CPU Optimizations

• Reduce Resource Locking

- Avoid locking/reading from a surface you were previously
rendering to.
- Avoid writing to a surface that the GPU is reading from, like a
texture or a vertex buffer.
• Minimize Number of Draw Calls

- Use degenerate triangles to stitch together disjoint triangle strips.
- Use texture pages.
- Use the vertex shader constant memory as a lookup table of
matrices.
- Use geometry instancing if you have multiple copies of the same
mesh in your scene.• Reduce Cost of Vertex Transfers

- Use the smallest possible vertex format.
- Generate potentially derivable vertex attributes inside the vertex
program instead of storing them inside of the input vertex format.
- Use 16-bit indices instead of 32-bit indices.
- Access vertex data in a relatively sequential manner.
• Allocate Resources Efficiently

- Create all vertex buffers, index buffers, and textures ahead of
time, and reuse them with DISCARD.

Thats what suggested NVIDIA .

As I said I would really like to see where is this huge performance drop as I described and showed above coming from...

You have to admit that what I have described above shouldnt be really like that.

nope

...14 :d

far away

Quote from Victor :

There's a new policy about this - we're not deleting them anymore. Only actual harmful content (how-to or a cheat itself) will be removed.

Ok....thanks for the info.

Sorry to saying that but I feel bad for for you as these cheating thread are really spreading too much.
General section looks too very messy

sorry to say that but that cheat(s) work currently on S2 servers as well.It least the guy who make it is saying he tested this and it works on S2 too.

Moderators please grab the replay and delete this thread.thx

Quote from tiagolapa :

Now i can imagine some real demo racers thinking about buying S2 and thinking that "nah this demo thing is awfull, full of cheaters... s2 must be the same" ... to make it worst, its portuguese work.... i feel sad

I think this is what make devs confused really most.I have already mentioned exactly the same in other thread.

I am pissed by this even more because now Scawen have to focus to get a fast fix on this and stop his regular development.

Hi all,
sorry it took so long time I just didnt have much time today in my job.
Lets start the speculation...

Quote from n3o :

Well that cheat that was posted by the other guys isn't mine, infact mine has an interface preety much like the old lfstweak, which wasn't posted, coincidence or not, really odd i would say.

The keylogger virus you saw on the other file, isnt a keylogger lol, its a dll used for the program to check the keys pressed by you ingame so u can activate the cheat by pressing a button. Mine is not like that though.

As for the 680km/h shot, that makes the car break apart, its not to be used, but its possible to get a 3xx km/h with the gti lol.

Im glad a developer can come up with a protection real soon, as this wasn't intended to go online. Btw, we don't get an OOS cause it doesnt change any car variable, so its impossible to check it that way.

Its done with memory editing, and the only way to fix it should be implementing a scanner which scans the memory. But then again, its easy to write another program with different memory characteristics. Now that you know how hard it should be to solve, maybe u'll understand why i have caused all the trouble . Its a major security leak, and should be solved asap, if i didnt do it this way i guess it wouldn't put this much work to it lol.

PS: I dont mind all the bad racer comments, cause i just dont race i didnt even knew LFS, im a coder, i did this because a friend of mine asked me to code a version of lfstweak that matched patch U.

Take Care

Simple question.did you send your version to devs?

Oh, don't like the sound of that idea?

Well with S3 they will have to re-make the engine because the other titles will have already running possible DX10 and DEVs will have to compete somehow to attract more people buying S3.
I know that more important will be always the physic part but thats how is it going on the market.Eye candy brings money too

Quote from Becky Rose :

I think it's 12 timezones, how far do you think it is? lol... no really, very interesting to see the connection speed is possible but I pressume this is a special low contention ratio line that is super expensive to rent?

I meant thats its not too far away from the technical point of view.Well most of companies running a lot of their internal networks on our networks so they getting huge discounts for many things.
I cant tell really how much as this could be considered to breaking the company rules and I have signed papers for this but its way too much more they you pay for your home connection and with even slower speed then average ADSL speed avaible on the UK market.

Quote from DeKo :

you do know, that everything we have seen of crysis has been running on DX9?

I have already told him this above...but never mind

just have download to try this and this above post was deleted...Quick hehe:-)

Question:
Does this tool make the Hotlap replay getting OOS error or not?
I mean you use this tool.Make hotlap which is faster or closer to WR and you save the replay and when you lanch LFS U19 without this tool and play the replay does it give you OOS error?

If not then this tool should be banned and you should got warning.

Edited:the quote wasnt necessary so I have just a bit cleaned my post.

Scawen,
I think this is more question for you as you are probably the only one who can answer from where come this unefective drawing of models and huge drop of FPS on hardware which is capable to draw(with a good performance)beyond what LFS offer currently.

The help of graphic cards doing vertex shading is not fully implemented?Any bug in 3D engine or something else?Lack of optimisation?I really dont know.

I am not moaning about my FPS drop from 250 to 150FPS because I still have FPS which is beyond my eyes to notice.
This is really not the problem I would be thinking about however such a drop might be similar for less powerfull graphic hardware and for example when it drop for someone same way like 40 percent from 60FPS to 24FPS then it is a problem.Its just I cant explain my self these huge drops in any reasonable way :-(

Maybe the FPS drop at start everyone have is not really related to heavy physic calcuation with all the cars around but the the 3D engine which might have some issues.

This is really my pure specualation so I am not blaming LFS.Maybe just something to think about.

Hope we can get any feedback from Scawen on this.

Quote from P5YcHoM4N :

Dell change the pin order on their PSU's, so you cannot upgrade them (unless you have lots of free time), however, I know a few people who have run gefo6's on a Dell with the crappy 250w PSU.

Whats the PIN order has to upgradfe with PSU unless they use special motherboards for that as well.He could just simply replace the PSU.

Running GF6800 or the other cards on 250W is real suice if you want to burn your PSU not even talking about the other componnets.That was not really wise recomendation.

Quote from Takumi_Project.d :

;even those who have fast connections still have the same issue, cuz it's simply too far

Didnt notice your post earlier but its not really far as you can think.I work for one the company which have most of the worldwide fibre network and "we" are able to quarantee quite a low ping to the customer connect like from Australia to Europe.Sure they pay quite a lot of money for that but its possible.Around 90ms its quite easy.
The people with home connection are not able to get it because they have just regular connection from local ISP and that si something else.

I just want to clear the technical point here a bit.

Quote from cpachmann :

dx10 isn´t just a higher nr than dx9...Its a completly remodification of what was before. Just look at games like crysis, for example. Thats amazing, and its the first game running with dx10. Remember the first games with dx9? Not that big difference to 8..but with the later games...

Sorry but you are wrong.The developers stated that the current work in progress work on DX9engine with Shader model 3.0 and was schowcased on DX9 hardware which support this shader model.

The point is the LFS 3D engine is only DX8.DX8 support just pixel shaders 1.1-1.3 (but LFS doesnt using any of these futures currently)I think. DX8.1 support pixels shaders 1.1-1.4.Side note GF3 doesnt support pixel shaders 1.4 while ATI 8500 does.
The point is that the effectivity of Pixels shaders 1.1-1.3 in hardware is really slow and some effect are hard to achive due to limited lenght of the code whith DX8-DX8.1 hardware.This was approved a lot with Pixel shaders 2.0 and the complexity and lenght of the pixels shaders code in Shader model 3.0 was moved towards really high complexity.

There is no doubt that LFS 3D engine will have to be re-written probably by high ammount to achive really high effectivity as just adding DX9 stuff to the exisit would be probably possible but with lack of good framerates.I bet Scawen is not really happy about that and when S2 will be finished then we can see later in early alpha stage of S3 some DX9 stuff from Scawen.At later time he will be also at the point if DX10 will be really required or not.I wouldnt like to be in his skin.

I'll go now, had this one ready actually, but it won't take long for someone to get.

Its a Skoda car.Need to find out which one exactly.

Quote from imthebestracerthereis :

dont hate me cause I dont rock at forums like most of yall do be kind ok I need to know what happened to the car park heres what it looks like Thanks in advanced

-Dustin

Sorry thats my fault as we have been working on these textures Elektric Kar.
I will try to updated the missing texture till Thursday but no promisses as I am going on Friday on holidays so there is a lot of stuff to do before I can go.

Quote from filur :

Engine fix (twice!) in 0 seconds, online / in race.

how did you do that it takes no time?

Hi Sinbad I know its your turn but could I post instead of you

What kind of LAG is is exactly?A network lag or a graphical lag?
Maybe your internet just work worse today then any other day

Quote from a112 :

I have strange problems,accelerate funcion is kinda jammed,it's not the key,i remapped it,and it's still having issues.I tryed reinstall and nothing solved!It stopped doing that one time,but started again when restarted the game!

I really didnt undeestand what is your problem.
Please could you describe in more details what is it really your problem?
Do you use wheel(why you have then mapped a key to accelaration ) or do you keyboard to drive?
