Did a couple of laps in the Ferrari. I’m sweating!

Yadda · 12 Nov 2018 at 22:00

Lol, I can imagine!

Anyone want to buy a Datsun? One careful owner...

Edit:
Just tried the Ferrari, forgot to blink again. Wow. :eek:

Edit2:
This is gonna take some getting used to. Driving by my wits at the moment and just completed my 3rd full lap without an epic crash (there have been a few of those - note to self, leave the kerbs alone) - 6:02 (offline for now).

Christ, Nordschleife. Will have to give the transit a run after watching Guy Martin’s shenanigans last week...

I know the first third and last third, but the middle section with lots of different speed corners always catches me out.

Yadda · 13 Nov 2018 at 08:11

Hah, similar here. So far my knowledge of it is "there are some tight bits, some fast bits, some bends that are faster than they look, a downhill bit and an uphill bit, and not necessarily in that order". Oh, and "don't forget to turn off at the end because someone's put barriers on the track". (Yes I rammed them in the Datsun. Twice.)

Haha yeah, that's the tourist layout for you, lap ends at the gantry at the start of the straight.

Definitely more time to be had in the transit, see if anyone can get close to Sabine's 10:08.

Also, very weird going from my CSR Elite load cell pedals back to my brake modded G25s, brake feel is very odd.

I hit it so hard there was no getting it out, lol. I had to run the laptime "app" (from the r/hand sidebar) to see where the lap started and ended. From what I can see it's from the first overhead gantry to the last.

Can anyone else not resist a quick blip on the throttle to bring the back end around when leaving the pit space in the Ferrari? Great fun.

PinkFloyd · 13 Nov 2018 at 11:18

Ooooo Nordsclieffe, I'm going to have to make time this week for my favourite circuit. Just been so damn busy recently, away at the weekends, busy at work and planning a new kitchen in the evenings! :eek:

Nice going, Petey. I wish I'd known not to ride the carousel - you have no idea how many times I tried before eventually giving up and going around it.

I had another hour or two on it last night and have the first third-to-half down now so hopefully it won't be too long before I learn the rest.

I've noticed I get a significant frame rate drop in the same spot every lap - around 1:52 to 1:54 in your video. I've disabled MSAA in Sweetfx so my usage graphs show everything is now well below maxing-out but the issue persists. I'm wondering now if it's reading from the HDD (the game is on my hybrid drive not the SSD). Anyone aware of this issue?

Uncle Petey · 14 Nov 2018 at 11:04

Not sure tbh. I have it on an SSD FWIW, although a lot of tracks do have a couple of spots where fps can dip a little anyway.
I learned the hard way on the carousel too... Not sure about the mini carousel at the end, but I chickened out anyway.

Car setup if it helps:

Final drive: 10/48
Aero: 17/26 to stop it losing the back on a couple of flat out bends.
ARB: 110000/25000
Fuel: 15L

Thankfully the FPS drop happens on a straightforward stretch so it's not too bad, just a distraction more than anything.

Thanks for the setup tips. I haven't changed anything yet except fuel but was going to experiment with aero - there's a double-right hander in the first quarter that's a bit too sketchy flat-out in default trim, lol.

NeverWinter · 14 Nov 2018 at 11:55

I get no drops, but different GPU obviously.

I think I just lowered fuel a little and set to Q tyres and a couple of clicks off pressure all round.

Yadda · 14 Nov 2018 at 12:46

Cheers @NeverWinter. Judging by my usage graphs I don't think it's a GPU issue. Are you running the game off a SSD or a spinner?

NeverWinter · 14 Nov 2018 at 13:12

I think it's currently on an SSD.

Yadda · 14 Nov 2018 at 18:15

I think I've found the answer, and it doesn't sound like a HDD issue after all.

Someone else with the same card as me (actually a pair in SLI) has posted about experiencing the same issue at exactly the same part of the circuit. See post #15 in the thread below:

https://steamcommunity.com/app/244210/discussions/0/541907867751495469/

Usage graphs don't show anything unusual so it's not actual GPU or memory usage that saturates, instead probably the way the game manages textures with 3GB cards. Never mind, I'll turn a couple of things down for Nords and see if the problem goes away.

Perfect excuse to grab a 1060/70 in the Black Friday sales

Got my sights set on a wheel & pedals upgrade first but yes, a GPU is on the cards at some point... and VR... and a 1440p monitor (this 22" 1080p panel will be 10 years old next year :eek:

).

NeverWinter · 14 Nov 2018 at 23:12

I’d like a high refresh 1440 gsync at some point, see what all the fuss is about (have 60hz 1440p currently which was a welcome upgrade even over my 1920x1200 monitor). But I think a new CPU, board and RAM on the cards first.

Yadda · 14 Nov 2018 at 23:17

I was typing an update as your message was posted.

Turns out all I had to do was lower shadow detail/res or whatever down one click from max and it breezes through that problem bit of the circuit. Even with MSAA 4x enabled in Sweetfx.

So that's DSR x1.78 (virtual 1440p), 4xAA in game, 4x MSAA in SweetFx and all in game detail settings at max except reflections (I've not tried raising this since my day-one config actually), smoke and shadows.

That'll do for now.

Edit:

When you're learning the 2nd half of the circuit, trying Petey's setup, feeling your way through and you've been wondering for most of the lap if he's been a bit bullish with his ARB tweaks... and then you eventually realise you're still on default (medium? edit: soft) tyres.

I enjoyed the slide though...

NeverWinter · 14 Nov 2018 at 23:34

Massive diminishing returns on shadow detail, if I’m struggling with FPS in anything it’s the first thing to get turned down.

Glad you sorted it.
