Assetto Corsa Competizione Early Access Release 5 is OUT

[Enagee]

v0.5.0 Changelog
- New Emil Frey Jaguar G3 car.
- New laserscanned Circuit Zolder racetrack.
- New special events with online leaderboards.
- Fixed disappearing main menu UI in VR.
- Texture memory optimizations.
- Fixed a chase cam rotation bug.
- Fixed a TV camera bug.
- Car light improvements in TV camera views.
- New inertia calculation method and new more accurate inertia value (advice for setups, use softer fast damper to let the body move and settle, instead of having the car and wheels jumping)
- New motion ratio calculation for dampers resulting in more accurate values dedicated for each car.
- New ABS feature. ABS now never lets higher than 70% difference between left and right brake pressure. Improves behaviour on extreme torque vectoring, like braking and going through a water puddle with one side of the car, but can result in inner wheel locking if driver insists braking hard while turning into a turn. Might need more rear brake bias on certain cars.
- Improved ABS logic, resulting in better turn-in under braking, on certain cars (most notably modern cars such as the Huracán, F488, BMW M6).
- Improved TC off on gear-change functionality. TC is instantly switched off and on again when a gearchange occurs, in order to protect the engine and drivetrain from heavy vibrations, especially on situations where kerbs and the engine limiter are involved (part of real cars' TC logic too, occasionally they will even not allow the gearchange). Now the TC off timing is car-dedicated and optimised. Some cars might handle a gear change better than others.
- Improved tyre thermal model, especially wet tyres.
- Improved tyre grip when tyres are overheated, such as after a spin.
- More tyre wear when tyres are overheated, no free meal.
- Corrected bumpstop position and functionality of the Ferrari 488 GT3.
- New ECU maps for all cars. ECU maps now influence power, fuel consumption and throttle maps. Usually the lower number is the more powerful and has the most power consumption. After the initial 3-4 values, it switches to wet ECUmaps with similar power and fuel consumption but different throttle maps. Please check the official forum for all the released cars' ECU map characteristics.
- New launch control for all cars. Now with manual clutch, just engage 1st gear, put the clutch and accelerator to the floor and the engine will stabilize around 5000rpm. Release the clutch gradually while keeping the accelerator fully open to avoid stalling.
- Audio engine optimizations
- Fixed potential wrong volumes switching cameras
- Fixed time multiplier for the end race replay
- Fixed wrong trackmap cars position during replay
- Intro sequence updated

 

[Case_]

Regarding performance, be aware that you can still easily be getting a CPU bottleneck with ACC. You won't even be able to tell just based on CPU usage, but you can easily be maxing out the game's threads anyway. Case in point - it's very easy for me to get a CPU bottleneck on my i7 2600k even with an aging GTX 970 for one or two of the game's threads (out of three or four it seems to be actively using). My CPU will not be at 100 %, neither of my cores will be at 100 %, but my GPU usage will be like 70 % with framerate around 40-50 and it won't go any higher, because, if I look at the actual thread CPU usage, the two main threads will be maxed out.

ACC needs *a lot* of CPU power, especially if running with 8+ AI and in rain or at night, pretty much the most of the games I've seen in the past few years. And a multithreading CPU won't help as much as you might think here.

That, I would guess, is why people are getting performance so varied with the same GPUs.

 

[RasmusP]

What I like though: for me the gpu load seems to be pretty much the same in sunshine, rain, night and mixes of it all. Not like rF2 where you can have everything between 1500 MHz throttled gpu at 30% load and 2050 MHz dying gpu at 100% load and 40 fps if you hit a crucial spot on some tracks with too many cars visible...
So far, I like acc. Cpu usage is extremely high though and definitely a bigger problem that the graphics card in my opinion!

 

[Mitja Bonca]

Aston is indeed a great car, with some setup tweaking, I really started to enjoy driving it, and actually pushing it, like I am used to do in AC. No other cars (before Aston) didn`t give me that kind of feeling and satisfaction.
With TC on off of course.

 

[Patrick Panton]

Question for those that know, I notice in the trailer that there is a wind farm modelled, is that at the real track ?. Reason I ask is, if its not, why put it there ? surely things like that will just make performance worse?. I don't know about anyone else but I don't look at that rubbish when im driving.

Don't you mean Jaaaaag?

Google "zolder" and look at the west side of the circuit. You'll see the white pillars and especially the shadows of them.

[MarkR]

Zolder looks glorious in full 4K, truly realistic but... even at 1440 settings there is a strange blur and slight haze to the graphics, 1080 has the same look of a water colour. No settings other than resolution changed on 1080Ti so this seems a little odd.

VR performance, using 45fps, ASW on Oculus remains good for me. I’m surprised just how much elevation change there is at Zolder, sections that look flat on the standard monitor are so different inside the VR cockpit.

From the laps in hotlap and hotstint I’ve run it looks good. Looks like ACC still needs a £1500 plus pc to really play it as intended at the moment though (of course as always hardware prices drop quickly enough).

There is a wind farm on the other side of the river/canal, and there is a solar farm right next to a track. And I guess I have to ask - why would you think it would make performance worse? And I assume you mean performance of the cars?

 

[Bonehead]

I guess I'm one of the lucky ones. I just ran Zolder at night in the rain @ 2560X1440, with 20 cars visible. Every video setting was maxed out, and it was crisp, and ran smooth as silk. Full screen, V-SYNC, and Motion Blur were disabled. I don't know anything about computers other than I have a one year old HP($1,500.00 US) with a GTX 1070 card, and a new 32" MSI 144 hz curved screen. I hope in some way this helps someone figure out their video problems.

What resolution has this 32" monitor?
Has it gsync?
If not the answer is simple: you're indeed one of the lucky ones, but not because it runs so much better on your PC but because you're just not such an overly sensitive drama queen like some of us (me for sure)

2560X1440, and I have no idea of what gsync is sir. Being a computer 'Pud', I just plug it and play it.

 

[Ace King]

Superb MSI monitor which uses uses either G-Sync or Free Sync with a 1ms response time.

No doubt HP paired this with a Radeon GPU to benefit.

[Ace King]

I notcied when i reread his post and corrected it before you even posted. lol

It appears MSI makes only "Free-Sync" monitors so perhaps he should have made a different choice

 

[Case_]

But Freesync support is now coming to nVidia cards, even though somewhat limited, so it might be a moot point soon anyway.

 

[Ace King]

That would great if all previous/older Nividia GPU's would be backward compatable.

I believe it should be available for all the cards that support Gsync, so all the way back to GTX 6xx series. There's just the catch of very few monitors being officially tested and approved, while the rest might work fine or might exhibit some issues.

Also, as I've just noticed, the driver is actually already out since yesterday (417.71), so it's already here.

Quite right and I dip my hat to Kunos for having them there as they are in real life. I was getting at hardware performance, ive noticed that other racing games have had balloons and planes flying around and all sorts of things going on in the background and ive always thought to myself that its not needed and would just add to the rendering power needed. But in this case, its part of the track so fair play.

Ah, right. Should've realized I guess...
But honestly, I wouldn't expect these background things to influence the performance all that much on the hardware we need to run the game at least. Compared to what is needed for physics/AI calculations and for drawing all those high detail cars and reflections and lighting, a few fairly low polygon spinning wind turbines are unlikely to have a significant enough impact, IMO.
