New PC, Strange FPS.

[Simon Roberts]

Hello Guys,

Ive been out of AC for a long while (Last April) Due to us having twins (Now one!) so ive built a new PC.

Im getting around 180-200FPS with no other cars on the track, but as soon as i add AI or join an MP server my frames drop right down to as low as 30, should there be such a drop?

 

[Joao Alves]

Could you list the specs of the PC so we can get a better idea of what may be happening?

 

[Simon Roberts]

Its in my signature.

Post in-game video settings as well. For starters, I believe smoke is quite demanding, as well as High PP settings.

Firstly congrats hehe and about AC,well with your configuration it should work fine...From 180 to 30 that is a drastically drop and its not normal unless you have smoke at maximum and reflections to high aswell.
I`ve done a search on that CPU and found this.

• PROS
• Offers the best integrated GPU performance on any platform to date. Supports AMD's Mantle API, and heterogeneous system architecture (HSA).Better CPU efficiency than previous AMD APUs.

• CONS
• Total CPU performance isn't dramatically better than the chip it replaces. Intel cores still offer better CPU performance for the money.

• BOTTOM LINE
• The AMD A10-7850 APU's great graphics performance and new computer features are partially undercut by the CPU performance.

Im beginning to think that the CPU is just poor to be honest, I got it very cheap (£65) so its not a problem, will just use in another small machine, think i'll have to go back to Intel.

Ive ran tests this morn and on the line at Monza with these settings -

Fullscreen | AF 8x | AA 4x | FXAA OFF | Shadows High | PP MED | World Detail HIGH | Motion Blur OFF | RQ LOW | RRF LOW

I get 180fps, add in 8 AI and it drops to 60fps, go for full grid and its 30fps and 99% Occupancy warning, i think the CPU is just terrible to be honest, no way should be getting these sorts of frame drops. Im very impressed with the 290X though.

 

[Dinca Andrei]

Yeah sounds about right..CPU issue

 

[paracletus]

yes, cpu bottleneck it appears. although, it's surprising that the amd chip is performing that badly; could be another issue somewhere.
AI is cpu intensive - should be improved for 64-bit cpu when the game engine switched to 64-bit sometime in the future.
the graphics will easily cope with AC at any detail level.

 

[Simon Roberts]

Ordering Intel I5 right now AMD you suck lol.

 

[Dinca Andrei]

I have a i5 4440 @ 3.1 Ghz...i have no issue with full grid or more than 30 cars online.

 

[Simon Roberts]

Yeah my old rig was 3570k and had no issues, unfortunately it got damp in the garage over winter and corroded motherboard and killed CPU when I turned it on

 

[Dinca Andrei]

Ahhhh that is sad indeed....i feel for the CPU aswell hehe,now you know..PC are like women....if you dont take care of her "CPU" it will damp you

 

[Danny Irving]

It's definitely not a cpu issue as I use an A8-3870k which is a **** ton worse than an A10-7850k & I have no issue with the cpu at all. AC uses just over 60% of it.

Editing to clarify that the usage is in Multiplayer with around 15 or so people.

2nd edit, Tried a career mode race, averaged 80ish fps at Vallelunga w the Abarth 500. All settings max except AA (x4) but x4 sparse supersampling is on in nvidia inspector. I usually don't use the post processing effect but I did in the video below.

Apologies for this post but I feel as though APU's get really bad rep when they're not too bad at all

(I would have an I5 anyday over an APU though haha)

 

[Simon Roberts]

What frames are you getting and settings please Danny?

 

[Danny Irving]

What frames are you getting and settings please Danny?

Edited my post Simon.

I will edit my settings to reflect yours then I will post the results

Currently uploading video (Action! locked it at 60fps)

Check the cpu temperature in operation - it could have a problem such as overheating which would slow it down drastically (i.e. throttling & creating the "bottleneck"). The heatsink might not have been fitted correctly / and/or the thermal paste hasn't been applied right.

Apologies for the delay. Handbrake took longer than I thought. (Check the bottom left corner of video for fps)

I'm running an NZXT KRAKEN X41, CAM software reports up to 90 degree, BUT and its a big one, no one seems to be able to read correct temps except AMD overdrive and bios, AOD reports a thermal margin of 46 degrees and motherboard never above 45.

Danny than you very much matey, will look later when not on phone.
