ACC Graphics and Performance Discussion

I use Philips hue sync to synchronize Hue Color LED lamps with the screen. So a background program. Then I also get stuttering and it seems that V-Sync or G-Sync is not working properly. I fix this by deactivating the fullscreen optimization for AC2-Win64-Shipping.exe. "Steam\steamapps\common\Assetto Corsa Competizione\AC2\Binaries\Win64\AC2-Win64-Shipping.exe". Properties- Compatibility-
Disable fullscreen optimizations. I use fullscreen ingame. You can test if that changes anything.

 

Thanks for the suggestion! I'll try It for sure.

I Just returned the Philips hue play because in game, with Sync activated, the hdr stop working.
Furthermore i dont like to have a process like that in background, in High CPU performance mode It use 5% of CPU and 5% of GPU..

 

Alone my GPU is at 100%, but with AI, my GPU can drop to 70-80%.
Do I need to upgrade my CPU ? I don't see why I should by a new GPU for +25% perf if my GPU only used at 80% sometimes...


I play at 1440p, with i9 9900K +2080ti, is the GPU always at 99% ??

 

Radeon vii is seriously underperforming. Running 3x1080p at 95% resolution scale. All settings low with the exception of visibility range and shadows on medium. Graphics are disgusting. Hovering at 50-70fps in multiplayer racing. night/rain is unplayable altogether.

I could live with the game looking like a mid 2000's sim, but not at this performance level. Please fix your game before throwing out dlc (again).

 

I play at 1440p epic...the game looks gorgeous. It's the next gen graphics
I have some drops to 80% gpu usage. I wonder if it's my cpu.
You need maybe 3080ti and i11 9900k to play at epic with your triple.
You are hardware limited....it's not the ACC's fault. Sorry

 

I have a 3900x 32gb of fast ram and a 1080ti and I have all settings on epic, car lod at 100% and can run with around 30 AI day or night and get around 80fps with occasional dips into the 60's. I do run only one 34 inch ultrawide though.

 

I have a vega 64 LC with ryzen 5 OCed i can run 60fps at high settings on triple 1080p and with freesync its smooth when struggle to maintain high fps

But to achieve this i had to OFF the triple screen setting because its a 10 to 15fps hit when enabled

 

A game can utilize most of your resources and still be poorly optimized. The poor performance is definetly a ACC/Kunos problem, not a hardware problem. The fact that you use a 2080ti/9900k to play the game at 1440p kinda solidifies my point.

1080p triple screen amounts to around 6.2m pixels. That's
1080p at 300% resolution scale,
1080p uw at 225%,
1440p at 170%,
1440p uw at 125% or
2160p at 75%.

There's no way you're not dipping below 40 to 50 fps while racing vs ai or multiplayer. No freaking way.

 

I forgot to mention I run at 150% resolution scale, still less than what you showed above

 

The 3900x is like the 9900k.
Do you have 99% gpu all the time ? I want a new cpu or gpu but don't know if it's cpu or gpu issue.
It's probably the cpu cause my gpu has some drops usage to 75%

 

The game is so gorgeous...the graphics are demanding. There is no equivalent quality. Even pcars 2 look awfull compared to ACC.
With new games, even the last gen hardware are not enough powerfull, read dead 2 at ultra is more demanding....it's finished the time where you can play at ultra with +5 years old cpu/gpu.

It's not the old ISI enhanced engine from 2006 like Iracing or Raceroom....

 

ok I have received my i9 9900K, GPU always maxed at 99%, it has fixed the GPU usage drops to 80%.
Case closed for me, and the 16 threads are used in ACC

 

Yes the GPU is usually maxxed out unless I use a fps limit, even then it quite often sits at 99%

 

but do you have like me stuttering or micro freezes with x24 or x48 time acceleration ?

 

Just for AMD graphics card users.

Lately I got micro stutters and found out it's caused by the anti lag setting in the driver's setting. Micro stutters gone. Driver 20.1.3 here.

 

No I don't, I run the 48x time multiplier and don't get stutters at all. I have a gsync monitor, maybe that helps.

 

I have gsync too. Strange. It can't be the cpu i have now the i9....

 

It all seems pretty random, hopefully they find the cause and can fix it quickly.

 

Can tell me how much fps i will gain from 1080ti to 2080ti at 1440p ? (sorry for double post)

 

I wouldn't know as I am on the 1080ti never ran the 2080ti.
You are probably better to hang off a few months to wait for the 3080ti, that is what I am going to do.
