AC on a single GTX980 at 3x1440p, what perfs ?

Hello racers,

My specs :
GTX980
Core I7 4790K running at standard 4Ghz
8Gb RAM

Right now i have very-stable 60FPS at 4k on high (not max) settings with many AI.

What graphics performance can i expect in AC with a single GTX980 at 3x1440p with 10 AI ?

Thx

 

I used to run triple 1440s with a single 980, pretty easy to hold 60 of you drop reflections to low/static and shadows to low with overall PP effects set to normal. That's for racing with a ton of cars on the grid though. You can bump up those lowered stuff by a bit if you are just hotlapping. 2xAA should do fine at 1440, wouldn't suggest running any higher with triples at that resolution. Mine were 24 inch monitors running 1440 so I could bypass AA completely as I barely saw any major jaggies due to the higher pixel density on the smaller monitors. But for 27 inchers or higher you might have to use 2xAA just to be safe.

Although, I could suggest you a simple test to check the performace for yourself without having three monitors attached.

- Grab Simple Runtime Window Editor (SRWE tool)
- Start AC, change the settings in the launcher to 1440p in borderless windowed mode, single screen rendering mode (those two are very important)
- Start a race session with a bunch of cars on it
- Run SRWE in admin mode
- Select acs.exe in the list of open programs tab
- Then change the resolution from 2680x1440 to 7680x1440 by inputing those values in the corresponding boxes and click apply
- And now the game should be running at that resolution
- Do H center and V center so that the game centers itself to the middle monitor
- Check what FPS you get
- Profit

 

Bleh... was half asleep when typing that. Meant to say 2560x1440 to 7680x1440, not 2680. Goddamn, should always double check before pressing reply. xD

 

Awesome answer thank you so much.

I never heard of this tool ! Great way to test config perf before buying monitors !

 

No problemo, if you get any doubts just give me a message and I can give more detailed help if needed. The SRWE tool is actually a pretty neat thing indeed, but a tiny disclaimer would be that the performance numbers that you get out of it are gonna be a bit higher because of its requirement of having to run the game in single screen rendering mode. When you do however run the game with three actual monitors, you'll end up using triple screen rendering mode in order to get rid of the stretching and warping of the image on the side monitors and in that mode you'd lose about 5 fps on an average compared to single screen rendering, around 10 given an absolute worst case scenario from my experience. Not anything to actually worry about though if you are only aiming at 60FPS gaming at that high resolution, as long as you keep the eye candy in check the 980 has enough juice in it to handle the load just fine.
