iRacing Season 1 - Lime Rock (no chicane) - Jan 5

[Ken Murray]

So on the next straight Simon came storming through, and when I tried a move round the outside at T1 Tommy nipped past too!! The next lap I repayed him the compliment, but I must apologise because it wasn't the cleanest of moves, soz Tommy.

You scared me a fair bit there, Kenny. But since you were faster I let you go.

You weren't that much slower Tommy, you hung on in behind me and it looked like you were closing before you went off.

Like MJ I also suffer fps hits during hosted sessions only  , just not quite as bad as him . So thanks for that info Pops, I'll see how it helps next week

[Ken Murray]

but I was amazed at Simon's pace on his original set of rubber.

I could go for hours in the Skippy and do the same lap times at the end as the beginning, I never wear much out of the tyres in that car, it doesn't have the power to do it. I finished with at worst 94% left on my tyres last night. I never struggle to go fastest near the end when I have a lighter fuel load.

I think the trick is to never lock up and don't turn the wheel as much, but I just drive it however I drive it.

I don't know what it is about my driving style then, I don't think I'm particularily aggressive. It definitely feels very easy to do a fast time in the first 2 or 3 laps with new tyres though, without having to concentrate too hard at not crashing. After that the actual times don't drop dramatically but the edge seems much narrower and you seem to have to be much more precise to get those times.

It's likely though that the hosted sessions are the only races you've done with big grids and with races as long? So I doubt it's to do with it being hosted, just that there are more cars and longer races and therefore you need more replay memory or whatever is it.

I really enjoyed that race

Unfortunately, my domestic situation means I can't join until around the qualifying start time and it always takes me a good while to get into the swing again so I was way off my PB.

I think that was possibly the best start I've seen in one of our races, everyone in front seemed to give lots of space and were happy to hold position into T1, no rash moves, so that was great.

I managed to self-spin going over the hill on lap 3 and had to wait for everyone to pass before I could rejoin dropping from 14th to 20th, then drove really well to eventually finish 10th.

Ade and Pete looked like they were having a good scrap which let me close right up until Ade slipped past Pete and promptly disappeared, good drive! Pete unfortunately span to let me past, pity, I was looking forward to a good scrap there, we were very closely matched.

The highlight was a chase with TT as the end, I think he span, rejoined behind me, easily caught and overtook me, pulled that gap out to 2s when I then started pulling him back to finish only 0.5s at the finish, not sure if your tyres were going off TT?

Thanks to Paul968 at the end, for not lapping me, I think you must have eased off a bit to let us scrap it out

I've been doing hour long silverado oval races with 20 drivers no probs. On hosted sessions, it doesn't need that many to start suffering.

[Paul968]

oval races may be less graphically demanding though because the drawing distances are shorter.

[Paul968]

Quite a straightforward race for me in the end. As others have said, qual was not the best in terms of drivers joining or rejoining the track, so it took quite a while to get a decent lap in. With F3 it should be easy enough to check if there is anything coming along behind, and if your lap is ruined (or is an outlap) why hold someone else up?

Anyway, I got a good start from pole, with the Kerbies having the top 5 places  Brendan hung on at about the same pace, but things got mixed up when we lapped Mr Oily as I had to wait a lap to get past and ther gap came right down. Behind there was carnage as Oily's spin caught Ian out and mixed up the others in the chasing pack. We gradually eased away until Brendan's unfortunate phone call (thx for telling me that - there was I thinking it was my driving making the difference  ). The 2nd half of the race I was on my own and could ease off a bit. Even so, it's not easy to drive Lime Rock slowly, so it was a delicate balancing act. At the end I backed right off to not interfere with Pops and TT but Brendan was a long way back so it didn't matter. Grats to him and to Bernie on the other podium places. A 1-2 finish for the Kerbies was a nice bonus and barring catastrophes should give us the team title.

On my G15 keyboard it shows the CPU usage for each core and always with iRacing it tends to be running both quite heavily, i think its around 80-90% usage for the cpu as a whole but normally one core is flat out. I'd imagine it fluctuates a bit for most people but maybe there systems are able to cope with it a bit better before dropping that low.

On my system the fps fluctuated alot normally droppping 30fps onto the main straight and the start was with 60fps for me. And I didnt think my PC was that quick now. C2D 2.4Ghz, 4gig ram, ATI4890

To be fair, LRP is a very short track and it was very difficult to find enough space to get safely out of the pits without getting in anyone's way or getting run into by other cars trying to leave the pits. During practice I resorted to squeezing myself out in front of cars I knew would be slower; in qualifying I was lucky enough to make a dash for the exit and get out 3rd behind you and Stuart, both of whom were faster.

I'm seeing 80-90% as well now that I'm doing 5760x1080, even with almost all the detail at minimum. It mostly gets 70-100 fps but does stutter occaisionally. C2D E8400@3GHz. Upgrade most soonly I hope!

Yes, but people were waiting almost on the apex of T1 rather than further back in the pitlane, which meant that they were slow in T1 and also forced passing drivers to run wide. My main complaint though was people rejoining after an off - fair enough if you can do it safely, but rejoining the racing line when way off the pace just as another car comes by isn't great manners.

I'm running a lowly Pentium D 3.4ghz with an 8800GTS at 1440 x 900.  With V-sync on I get a rock solid 60 FPS with everything on except shadows.  However, last week in the Dallara the FPS was dropping to about 52-53 which was giving me the stutters.

Have you guys tried using the GameBooster program which shuts down unnecessary processes?  You may be lucky in that it might close down the culprit that appears to be hogging your resources.

[mr_oily]

things got mixed up when we lapped Mr Oily

Yeah sorry if I held you up there Paul - I just don't have the same confidence/ peripheral vision with the Skippy I might do in some Simbin cars and didn't want to risk moving off line/ slowing up only to be collected by your extra pace. I know when I'm lapping (the distant memory that it is!) I always prefer some predictability so decided to drive as normal and let you make the move when you were ready. Any other track and it would have taken a corner or two but it's a little tight at LR isn't it!

[Mark J]

I've said it before and I'll say it again - you're describing all the symptoms of another process running, stealing CPU and causing the Logitech Profiler to lose track of what's running and revert to the default steering lock.

Can't remember which bar is which but one is latency, one is quality (packets getting through) and one is skew (how far out of sync the server and client clocks appear to be). If you're PC is too busy to talk properly one or more will almost certainly go red.

i checked this last time it happened Dave, there were no other processes running that could hog the memory/resources other than the usual xp things like svchost.exe (what is that and why are there several of them?). No anti-virus etc running, no scans/schedules. Its bizzarre. Last nights looked more like i was running a ropey internet connection but could just have been extremely choppy gfx once it lost the plot. I dont understand it being smooth as silk at 86fps then like a switch, losing everything down to 25fps after random amounts of time. Have held off buying more RAM to help, as may go for a complete mobo/cpu/new ram bundle i5 etc..just hate the thought of another full reinstall with the gazillion tons of software i have installed.
Don gave me an app to hard test the dual cores so may give that a try.

Am also wondering if the steering problem and this fps drop are related. Could it be a memory leak of some sorts? I'd guess that the majority on here are using a G25 though. Not sure what the answer is to remedying it  remove all Logi drivers and reinstall wingman ?

[popabawa]

Did you read my post MJ, I think that's a possible cause.
