UKGTL Season 15 American V8s - Lime Rock - Feb 16

[Stefan aka Postal]

Downloaded and installed this track yesterday evening. Went online for some laps and was running fine thanks.

Funnily while fiddeling with the graphic settings to tailor to my new screen resolution i found my framerate improved enabling the AA level at the config program. Seems my current GPU (radeon X800) really outperforms the CPU (Athlon XP2000+).

That's quite old kit Postal. I have an XP2000 with an Nvidia 6600GT that I used to use, but was retired to being a samba server
years ago  the X800 will likely cope with more than the xp2000 can throw at it. This game is single threaded so dual core
doesn't help you.  :'(

Matt, where do you have the single threaded info from ?

I have for years been using a 'set affinity' program to start GTL, which should supposedly make it use more than one thread, but maybe that is superfluous ?

One the other hand, I'm not sure this old game is even maxing out one thread of a newer CPU, so may not be necessary at all (but with Postal's older hardware, it could perhaps make a difference ?)

Cheers,

This utility is helpfull too https://www.simracing.org.uk/smf/index.php?topic=12160.msg218224#msg218224

You can just say i have an ancient machine Matt. i wont take it personally! I know about the single core thingy. So i got me the fastest XP processor my Mobo would accept and overclocked it. Added some extra RAM memory and the X800 GPU. Was nice to do some pc improvemend myself. It will have to last just one more season as i am looking into buying a new(-ish) wheel first.
So yes in my case these settings can have substantial effect on framerate.

Chortle.
My comment about old machinery was more that I do try to not use tracks where the frame rate becomes undrivable
on older systems. I sometimes wonder if i need to.

@Erling: Have a look at this screen capture. it shows a spike as taskmgr starts, then a lap at Pau, followed by selecting a different track
and car, then a lap at Groen(something)ring in a yank tank. You can see that when on track the game maxes out one core
and between tracks it is just "busy" The other core is doing some background stuff, possibly network or disk access, but is not
running the on track game as such.

If you fire up a dedicated server on a 4 core system (our server is 4 core) then it only every uses one CPU, and it goes to 100%
as soon as anyone joins, however fast the hardware is.

I don't know how microsoft CPU affinity works, but in VMware if you set CPU affinity it always a bad idea because it forces the thread (vCPU
in that case) to have to run on one physical core, and share it with other threads, even if other cores come free.

Interesting info Matt.  Think I'll try a test myself when I'm actually 'driving' in the game - playing back replays barely registers on the CPU usage.

With regards to stutters, I've discovered that it's apparently car-dependant.  My initial testing was done with the Challenger, and it stutters - it's even noticeable in replays.  Some of the other cars tested later does not have this problem; the graphics being completely smooth - again visible in replays.  Of course your mileage may vary, but it's the case for me.

Cheers,
Erling

No stuttering for me in any car.

Hi Guys. Just though I would say a quick hello. Have just joined up and am aiming to be ready for tomorrows race. Am racing as ccstevecc. My driving is hopefully better than using forums so I hope this message appears in the right place.

Sorry guys, but i can't join tomorrow night.
Is the birthday of my father and we will celebrate until late.

Have fun guys!

Is anyone able to help.

I am having trouble with pitting at Lime Rock. I suspect I have Autopit on, although I cannot bring the car into the pit box. Instead it parks itself about 20 yards further down the pitlane with no option of a board coming up.

I have read the post 6 November about the "player profile" reading Autopit=0 and Force Autopit=1, but I do not know where to find this.

Any help would be appreciated.

Steve, you shouldn't need a pit stop in this race. Also please read this post https://www.simracing.org.uk/smf/index.php?topic=11812.msg212761#msg212761

Thanks for the info and will check out the .plr location later.

BTW have you tried to join our online track yet?

Welcome Steve.
 Provided that you put enough fuel in, and don't sustain any damage during the race you won't have to do a pitstop. Avoiding pitstops is essential for me as my pitcrew are most unreliable and my race has ended whilst sitting in pitlane in about 90% of my visits there!!  If you want advice on pitstops.....do NOT ask me  lol!!


I only took a look at Lime Rock in GTL last night, thinking that I knew this track from GPL and so did not need to worry too much. I now understand Erling's comments!!!  

This GTL version has about 50% of the width of tarmac found in GPL. I think that there will be a few paint samples exchanged and maybe even a few door handles??
