Title: UKGPL Season 38 (Spring 2021) 1967 Sports Cars - Dundrod - Feb 26
Post by: Cookie on February 23, 2021, 10:38:52 AM +0000
Season 38 - SC67 - Lola vs Ferrari Cup – Round 4 - Dundrod

WIP

Round 4 of the S38 Lola vs Ferrari Cup takes us to Dundrod in Northern Ireland.
The Dundrod Circuit was first used in 1950 for the RAC Tourist Trophy Sports Car race and for the Formula One (non-championship) Ulster Trophy. The Sports Cars raced again in 1951 through to 1955 and the Formula 1 cars from 1951 through to 1953. The circuit comprised public roads closed for racing including a section of the B38 Hannahstown Road between Glenavy and Hannahstown, a section of the B101 Leathemstown Road from Leathemstown Corner to Dundrod and a section of the B153 Quarterland/Tornagrough Road from Cochranstown to the road junction of the B38 Upper Springsfield Road/Hannahstown Road at the Lindsay Hairpin. The last car race held on the Dundrod Circuit was the 1955 RAC Tourist Trophy race (https://en.wikipedia.org/wiki/1955_RAC_Tourist_Trophy) in which sadly there were 3 fatalities. The narrow, high-speed nature of the circuit, meant it was just too dangerous and since then it has only been used for motorcycle racing.

In view of the fact that fatal accidents can easily occur on this track, the shift+r is not limited


Please check the Season 38 details (https://www.simracing.org.uk/smf/index.php?action=LM2R&group=1262&theme=6) regarding rules and the Lola vs Ferrari Cup pages (https://www.simracing.org.uk/smf/index.php?action=LM2R&group=1312&theme=6) in particular.
In order to add an element of realism, and to hopefully reduce the possibility of rear-end incidents, the brake light patch will be used (http://srmz.net/index.php?showtopic=13319&#entry145626)  :eek:

Race List =  IGOR
Server = UKGPL_8
IP Address = TBA
Race date = 26-02-2021
GPL mod = SC67 - Lola / Ferrari only

Handicapping

"Works" drivers will carry extra weight in form of 10 gallons of race fuel (to remain in the tank after the race). No limit in quali!
Drivers are expected to behave in a fair and gentlemanly fashion and declare how much fuel they have left after the race.

In order to ensure there will be 10 gallons of fuel left after the race, the minimum race fuel load for Works is expected to be:


  • Lola T70 = 27 gallons (~102 litres)
  • Ferrari P4 = 28 gallons (~106 litres)


resets will be allowed (there is no need to carry out a Stop and Go in the pit lane if you make a Shift-R).

Drivers are reminded that Lap 1 incidents carry an extra 1 place penalty.
Only reported incidents will be moderated.

Please restrict chat to emergency messages only including at the end of the race until ALL drivers still racing have crossed the line.

Clive the main thing is the name of the track directory Dundrod (NOT Dund1950)

Jim Pearson gave a graphical update at last Xmas but track is same.

I will start the server now

Yes that's right Clive. We use the earlier version with the Leathamstown bridge for the 1955 cars. Not just because it is more authentic for that period but also because without the bridge to slow the cars down, Deer's Leap would be insane in the 55 cars. The 1965 layout is also prettier after Jim's amazing update.

The update is excellent and transforms the whole track, very green and realistic everyone should make sure that they have it installed.

I only did a few laps when I discovered the "missing bridge" section, just in case I was practising the wrong version, but the biggest challenge  I discovered is that jump in these big heavy cars.
In the 65's and F2's it is almost flat out, but certainly NOT in the GT's lol, at least not with the setup that I was using yesterday. I think that the suspension needs to be stiff enough to withstand the landing, but not so hard that it makes the car too twitchy for the rest of the lap............some testing still required.

You lot are worrying about missing bridges, trees and pings. I'm more worried about the narrow grey line of tarmac which you have to keep the car on. It's hard enough in practice so goodness only knows what it's like to race on.

Hope all goes well tonight.

I have decided to stay off the track tonight.  I don't know Dundrod well enough to feel sure I wouldnt be either a danger to others or just become a rolling rear end roadblock.

Also very tired this evening so would have struggled to concentrate.. a bad mix for friends on the track.

So hopefully no collisions or crashes and no disco's etc ... have a good race guys and see you later.

Well that was a disaster for me. I had a good practice with Mark Jones before the race. We could circulate in close company no problem. But in the race I got a couple of practice laps posted and then the server stopped recording my times. Then I had a disco so I rejoined again. My times were still there. I hoped everything would be OK. But despite putting in a better time (high 1:34s which for some reason has not been saved in my fastest laps?) which would have put me in P4, I was not registered on the grid. So with 4 mins to go I decided to quit and rejoin with a different helmet colour so the server would consider me a new driver. I tried to put a qually lap in but I was so wound-up I crashed. So ended up at the back of the grid. So I was resigned to trying to pick my way through the traffic on a very hard to pass track. Noticed frame rate dropping badly which it hadn't done at all in practice. On Lap 2 I was behind Evil when it looked like he made a mistake at Joey's Windmill (I think) and I thought I was going to get through when I got another disco.

I'll have to do some investigation. Something is not quite right.

I've turned off Anisotropic Filtering in NVidia Control panel and had no problems for over a week. No freezes since. Try it .

Great fun tonight. I guess that this is one of those mod/track combos that makes perfect sense. Tricky cars at a tricky track but very rewarding when you get it right. I made a fantastic start jumping Tris into 3rd place. Too bad that we bumped a few miles down the road and we both had to work our way back up the field.

Still, a lot of fun. See you a Spa.

( I can't see any points for the Privateers)

No, it was not me.

Sorry for my bad start, I had some troubles with my gear lever and I had to try twice before engaging the 1st gear.
Hopefully, I was at the back of the grid.

before giving up GPL completely, I try the pete BENNETH solution, (anisotroping), but it will be the last one.

afterwards, i know that i need to have my computer checked by a specialist,
but it's not in my budget for right now.

I'm very disappointed too but I think we need to be careful not to jump to the wrong conclusion. In my frustration last night I posted that I had a screen freeze when in reality I hadn't. No amount of screaming at the monitor (which I did a lot of yesterday), hammering the keyboard or throwing the mouse is going to fix the issue. There are 3 ways on-line races end prematurely:
  • Crash to Desktop (CTD) - GPL stops mid race, shuts down without prompting and the user is returned to the Operating System (desktop) not iGOR.
  • Screen Freeze - GPL stops mid race, the graphics appear frozen and the sound turns into a buzz that increases in volume and pitch. The only way to get out of this situation is to use Task Manager to kill GPL or to do a hardware reset (i.e power off the PC).
  • Disco - The client is disconnected from the server. GPL stops mid race and returns to the GPL Multiplayer menu. The user can then close GPL using the normal red button and the user is returned to iGOR.
So I think we need to be careful to make a note of exactly what happened. Because the remedy in each case will be different.

A few weeks ago I had an issue with my Thrustmaster T300RS Steering Wheel reverting to default rotation every time I powered up my PC. The button that allowed me to set a different default was greyed out. It is fixed now but it wasn't anything I did. There must have been a Windows update that fixed it (and probably an earlier Windows update that broke it!).

I'm just wondering if an update is at the root of our problems here? However, I know drivers use different operating systems (Linux, Win10, Win7 WinXP) so it would be interesting to understand what the common factors are.

Perhaps I should clarify what happened from my viewpoint.

A couple of seconds before my exit I had a sudden drop in frame rate ( down to 25-30fps? ).  I missed my turn in and was expecting the corner to be difficult, but I never got to find out because I had a CDT.

No screen freeze, no Igor, just straight back to Windows desktop....race over.

Axel's timings from the server are interesting. AFAIK Phil was close behind just before my exit. But it is strange that he appears to pass me as I vanished, but then despite not being there I manged to overtake him??...bizarre ???

Me too, Phil, am very disappointed for you.
for your analysis, it is indeed the 2nd remark: screen freeze.
that's exactly it.
that's exactly all the symptoms you describe. There's nothing else.

once in a while I can accept. But 9 times out of 10, no.   >:(

Yes bizarre  - but you must have had a lag that was longer than this second! As the server tries to predict your moves itself - even when you were gone...

PS

real Freezes  are track related only! Your wheel taps in an infinite gap in the tarmac as he needs an reaction of the tyres ...
It expects 60 times per second a feedback from the underground.

I'm pretty sure my problem was a network issue, quite possibly caused by me having UKGPL04 and UKGPL05 both running at the same time I was racing on UKGPL08. I can't find any evidence in the server logs etc but having 3 machines running different races through the same router is probably not a good idea. It wasn't intentional, I'd simply forgotten UKGPL04 and UKGPL05 were running, I won't do that again.

As far as turning off anisotropic filtering is concerned, I won't be doing that because I don't think my problem was graphics related. However, I did try it for interest. I found the kerbs more pixelated without anisotropic filtering. The GPU is doing less work with the filtering off so maybe that will help with Screen Freeze in situations where the GPU is struggling?

Yes Phil, imo you were taken out by the disco of Clive - I doubt that 04 + 05 had anything to do with it,
but when I have a race server running I do not allow any net traffic on any other PC too.
TBH the data volume of a client is tiny and even a full server needs only 1-2% of the possible net load. I think Dave does monitor such things...

AF was allways maximum here since we got GEM+ and GPUs like Geforce 2 and 4 were en vogue... ::)

Yes, the traffic involved seems pretty light; especially if the servers are otherwise idle/no connections.

Looking back at the recent Monza67 privateers race (21-Feb, UKGPL_10).
I see 16 driver sessions, outbound traffic from the server is approx 1.1Mbps, inbound 210kbps.
(This also includes Teamspeak & local monitoring traffic for related servers).

Cheers,
Dave.

Hi Philippe, where have you installed GPL and GEM? If inside C/Program/86x  try to unistall everything, included GEM and reinstall both outside Programx86 with administrator rights; create a new folder in C for example, or in D if you have multiple partitions of HD. May sound strange but  Win10 it's a nightmare and files ( especially third party ones like GPL mods or GEM) could get corrupted, or simply, even if you have full administrator rights, it's not true and for example GPL could not open a .dll because in reality has no full permission and then freezes. Turn off any updtates of win10 ( you can only delay by 7 days) on race weekend, win10 updates kill literally your connection and CPU resources , and turn off the chat when driving. Have you tried to enter the race via GPL multiplayer instead of IGOR? Do you have and Invidia GPU? maybe the problem could be related to some settings. I don't think ( but you can try) it's antialiasing fault, i have a GTX 950M on my 2017 laptot and i can run whit full antialiasing and anisotropic filter a 60 fps, i just reduced the detail to 35 inside GPL.
