which GPU is best for AC?

[Tim Meuris]

nvidea or ati?

What res are you running?

I didn't want to start a new thread to ask this so gonna drop in here. I have an iMac 2011 core i5 running at 3.1ghz. The GPU is a 6970m (mobility) with 1gb vram.

Would an upgrade to the same iMac with a 2gb 6970m be of benefit in AC. I don't have the funds to replace the iMac with a 780 model so this minor upgrade for minor outlay (say €50 odd) is my only current option. Cheers guys.

Nope. RAM doesn't improve GPU performance unfortunately

Might do above 1080p

Cheers for the swift replies guys. Also sorry stupid mistake not to include the res. I run triples on either 5040x1050 or 5760x1200 depending on the fps I'm getting on individual tracks and cars. Varies between 45fps and 55fps odd.

You will deffo be swapping memory with 1gb then at them resolutions, I also run triple and rack up around 2.6gb on my 780. Might help a little.

Ah now we know the full info then yes it will probably mean slightly less of hit to the cards performance over 3 screens on like for like video settings - but technically the GPUs performance will not increase.

I read the post as 'benefit to AC' so thought we were talking about boosting quality settings and stuff

 

[Juris]

Thank you guys. Really appreciate the help. Now I just need to find a GPU that makes me stay on the tarmac instead of playing chicken with the armco

 

[Simon Roberts]

Dont buy a 780 then

I used to use nVidia, but AMD caught my eye a few years ago and I've been using them exclusively since. Many of the AMD cards feature smaller 28nm technology which I feel gives their cards a longevity edge. Catalyst impressed me right away with the user friendly interface that simplified graphic adjustments--less sophisticated than nVidia, but faster to set up and leave alone IMHO.

The high middle grade and high grade card from both companies perform flawlessly...so it's really the little things that you have to choose between. Anything Radeon 7790 or higher, or GTX 580 and higher will be able to run AC with little to no problems, esp when AC 1.0 comes out with all the features.

I wouldn´t worry about a new GPU at this stage.
If it helps, i have Titan Sli + i7 4770 4.8ghz oc and still drop from 60fps 1080p at Classic Monza replays or when too much tyre smoke is produced on replays also.

Wow! I don't on my single 780 at 5030x1050, strange how every system different.

Apart from brief drop when lots of smoke.

yes mainly there. and classic monza replays are full of stutter in some cameras

I have never played on classic Monza in 100+ hours on AC haha.

 

[Slavko]

I think that best GPu for AC is 780 Ti or HD 7990

let us know when you do

780 ti is a must.

 

[GTAce]

Don't forget that the game isn't optimized yet, so there might be performance issues even on the best rigs.

 

[Pete Bone]

780 ti is a must.

Its not.

I run 5140x1080 on a single GTX670 and an i7 3770k and never have any stutters or FPS drops. I have the settings locked at 60FPS.

Having a clean and tidy Windows install helps things, gives the system a chance to run the Sim well instead of having other things to do at the same time.

Hmmmm, have you tried full grid at Monza? I ran a 680 SOC before my 780 and struggled to maintain 60fps.

Not Monza, i cant stand the track, its the most boring place i can think of but Silverstone runs perfectly with 21 458 S3's on the grid and tyre smoke at the start.

I'll give Monza a go though, purely for testing purposes and i'll report back soon.
