Assetto Corsa v1.5 Released

Paul Jeffrey · Mar 31, 2016

Kunos Simulazioni have just made available the much anticipated version 1.5 of Assetto Corsa for Windows PC.

The new update is available to download now via the Steam network and contains a number of impressive improvements to both the visual and technical side of the title.

Version 1.5 brings some interesting and highly requested new features to the title, not least of which is the new pitstop functionalities allowing fuel and tyre changes as well as damage repair in both single and multiplayer environments. This is big news for racing fans and will no doubt add another layer of immersion to the racing title.

On the physics side of things all cars in game have now been upgraded to bring all vehicles in line and using the latest tyre model introduced recently allowing "more realistic load sensitivity, a variable grip curve after peak, closer performance level between compounds, a brand-new surface and core heating model as well as more realistic heating operation range."

Lowest graphics = fps.

No...
Why would I get 60fps before the update and now 15fps with the same settings?

No they didn do anything that would change your performance. I have the exact same FPS as Before. VSYNC off, FPS limit = 60, and Everything is butter smooth.

I dont know if you did it already, but i would delete the AC folder in documents&settings, and then do a steam cache check. It could fix any issue you have. I hope it will, cause its super smooth here on a med PC.

I ended up deleting my whole install and redownloading to resolve some audio issues, maybe try the same thing although as @Alex72 says deleting your profile information and resyncing can also magically fix things as well. If you have a decent connection it doesn't take too long.

Nope. Baby sitter costs $20 an hour (factor in 2 1/2 hours, Bottle of wine about $40, That's pretty much $100 cold hard before we even order food. Entrée about $18 each, Mains around $40, desert or cheese platter anywhere from $12 each to $30 combined.

so, Approx $240 for under three hours. And it all ends up getting flushed.....

Could try taking her for a McDonald's, sure that's a little cheaper

My PC : 4GB ram, ATI Radeon 5770 Crossfire, QuadCore Phenom II 955...
Yes I know it seems old, but I could run AC with 60fps before the update...
(I'm talking Nordschleife on max settings and with any car with HD skins...)
I don't know what to do.

Your problem is that AMD 5770 has only 1 GB onboard video memory, it's actually pretty amazing that the original AC Nords worked that well. As you probably noticed, Kunos changed Nords quite a lot for 1.5, they added some more 3D grass and objects etc. So probably now whole track won't fit into 1 GB GPU memory anymore, which would cause horrible stuttering.

So the simple advice, buy a new GPU, you can find a better GPU than that for 100 bucks.

Nevermind, it works perfectly now.
What happened? No idea. It completely puzzles me.
And I still have graphic settings on max, except the reflections.
Oh about my card though.. Like I said, I have a crossfire system, so it's like I have 2GB and not 1.
So, yep, now I do run the Nordschleife very well! he he
Loving the new grass, btw. Way more realistic.

Now for a different topic...
I feel like I need to completely rework my filters.
Doesn't the game looks brighter than before? Or again, it's just me? lol
I notice that Wagnum updated his filters... I'll have to try it.

Oh and fortyfivekev, I did delete my entire folder in "documents".
Sheesh it was enormous. It had 150,000+ files... lol

Anyway, really enjoying the game now.

Yeah, that's not how crossfire works. Glad you got your game sorted though, have fun!

John-Eric Saxén · Apr 5, 2016

Nah SLI/crossfire doesn't add together individual cards' RAM, so it's even more impressive then how well it runs.

Regarding filters, it's indeed annoying that Kunos gambles with them on every update. It seems most people now prefer the "realistic" option.

Yeah I didn't write this correctly.
But you know what I mean, 1GB by gpu.
I know it doesn't add up, but believe me, I tried once to run AC without the crossfire activated, it was a HUGE difference.

Hmm,i have HD6570 and AC runs very smooth on my 8 years PC hehe,all in medium and no PP filters

Marco Waechter · Apr 5, 2016

Found out yesterday that Steam alone uses 25% of CPU usage under windows (normally it is 0-2 % usage without steam opened up...), resulting in overheating my CPU more quickly (resulting in stutters, and gradually decreasing until '0 FPS', not to mention it shortens the lifetime of the CPU as well) than necessary.
In offline and online mode of steam. This is a common problem, but though it is written about since five years already, I found no clear solution for this issue (tried already some advices -offline mode, for e.g.- with no efffect as soon as a steam game had been startet). Any clear idea how to solve this particular steam shi.te behaviour ?

Other than that, did someone notice that the Alfa Romeo 155TI V6 now has less diff settings available in the setutp ? Before v1.5 there was "center diff" and a "front diff" available, now this two settings are gone. Only the rear diff settings are left and in. Don't know if this might be the only car, or if some more cars might have been "simplified" in this matter as well.

I didn't try this car since 1.5 update, but from what you tested, did it behave well for what the car is? Kunos did say they are reworking AWD, so probably this car will receive updates in the future.

Marco Waechter · Apr 5, 2016

Ah, ok. Didn't even know that Alfa is a AWD car. Feels more like a RWD car since ever.
The Audi Quattro clearly feels like that (a AWD car), because it is (a quattro)

.

But since there are (or were) front and center diff settings, it seems to be an AWD car indeed.

I drove it in a race on Saturday, had been practicing earlier in the week and the car did change after the update. I thought it was a good change though, slid around a bit more and was more lively, really enjoyed it. Still had some AWD understeer but it's usually corrected with a dab of loud pedal.

Yes, it has four wheel drive system. https://en.wikipedia.org/wiki/Alfa_Romeo_155#155_V6_TI

Finally had the time to test the new update...
Well if I can call this a "test"...
Basically my game became unplayable cos it's 200% slower...
I don't get it...
I checked my graphic settings, everything seems ok...
I tried disabling stuff like anti-aliasing and reflections...
Nothing worked.
I tried using Kunos stuff only, not custom filters, etc.
Same result.
Any idea?
Did they change something major in the engine that makes it unplayable on older computers?

My PC : 4GB ram, ATI Radeon 5770 Crossfire, QuadCore Phenom II 955...
Yes I know it seems old, but I could run AC with 60fps before the update...
(I'm talking Nordschleife on max settings and with any car with HD skins...)
I don't know what to do.

I got an automatic driver update today by AMD and the fps drop disappeared with it. Important to set all anti- aliasing and stuff to zero (or set as "use application setting") in the AMD manager. But that being said, yes it seems more demanding now. I have set my fps locked at 50fps for better pc performance.

Ok, found out what is causing it: A process called 'svchost.exe (netsvcs)' which is going crazy as soon as Steam is opened up.. . Opening the win rescource-manager and disabling this particular process for the time playing AC, or other games, 'solved' it.
