Please help
 

I would like to play CLOD on its highest settings via bootcamp on my new iMac. On max settings I get many stutters over buildings and dense forest, I find low settings on both make it playable. All other settings I can play on max. What should I upgrade on my mac to achieve the highest performance on CLOD?

Intel Core i7
Processor 3.4 GHz
4GB RAM
AMD Radeon HD 6970M VRAM 1024 MB
2560 x 1440 resolution

i think my VRAM might be a bit low:confused:

Yes it is mate.

Keep most settings as you have them but not building amount or trees..set them to low/med

You won't get way with them on max with your setup I'm afraid..not until game is fully optimised

And that's a very high Res too

Your res is too high for your video card (which has too low memory btw for this game).

Try setting land detail, landscape shading, forest and special effects on medium or reduce resolution to 1680x1050. It looks great on these settings.

You can run it on max in 1920x1080 (full hd) res more or less with GTX580 3GB vram or maybe HD 7970 3GB.

You can run it on max on 1920x1200 on my gfx card (not 3gig VRAM)

S!

Will report back how CoD runs when I get my 7970HD..any day now :)

thanks for the info
I have tried different resolutions, i think the main reason may be the poor
optimization. Even if i try in lower landscape settings there is little difference from high settings. Do you think it is worth upgrading the graphics card or should i just wait for better optimization?

S!

Try these settings in Catalyst Control Center, work on my 6970HD.

Antialiasing: Application Controlled, Morphological OFF, Standard mode
Anistropic Filtering: Application Controlled
Tessellation: Whatever you prefer, game does not use it. I have on AMD Optimized
Catalyst AI: Performance, Surface Optimization OFF
VSync: On, unless application specifies
AA Mode: Performance
Triple Buffer: OFF, but does not matter as an OpenGL setting

In game make sure to have Epilepsy Filter and SSAO set to OFF. Use Full Screen mode and check VSync. I also put grass OFF as it has a FPS hit. Effects on Medium look good with less FPS hit that High. Forest on Medium/Low. Texture size on High, Original has a performance hit.Building detail I have on medium and their density on Unlimited.

Follow Ataros' suggestions. No way can you play it in native resolution of 2560x1440 with higher settings than ultra low.

Thanks for the advice, I made some changes with ccc.
Does anyone know if i can upgrade my imac graphics card to something decent? I don't have the money for a gaming pc :(
Flanker, will the upgrade to the AMD 6970M 2GB instead of 1GB and/or an increase to 2x4GB RAM be worthwhile?

^ this first
+ note that shadows and land shading have more influence than detail.

Extra VRAM may help a little but not with this res imho anyway. Maybe 2x HD7970 can handle this resolution it when x-fire is fixed.

Check out a link #8 in my sig and Performance section of this forums (sticky first).

S!

Having memory does not hurt with 64-bit system. I have 8Gb and it has been enough so far. Ataros, the 7970HD kicked 6990 and 580/590 in the groin at high resolutions as a SINGLE card in recent gaming test on Guru3D using Anno 2070(DirectX 11 title) so I think Luthier's team need to pull their code together in IL-2 if we want to see any improvement in FPS using SLI/CrossFire.

From my experience with ArmA2 visibility distance can bring any hardware to its knees. Most of the servers limit it to 3-4 km only to provide decent FPS while game allows 10 km max. And this is a 2 year-old game.

What is the visibility distance in CloD? When visibility radius is increased amount of required CPU and GPU calculations grows exponentially. This is a big issue.

S!

Yeah, very true. But again online you simply can not use full settings if want any decent performance from the server. LEt's hope the new GFX engine will be more streamlined and bugs fixed = more performance :)

I'd say don't waste any money on hardware until the next patch comes out. They said they are redoing the 3d engine from scratch. I'd wait for that and only after that look at hardware.

cheers Ataros
I read the performance thread and made some tweaks with the settings and gamebooster.
The HD 7970 is very pricy. I might just settle for the 6990, although I'm not sure if any of these are compatible with my iMac.
I won't be buying anything until the Battle of Moscow is released.

It is a dual-chip card. I would never waste money on any of them for many reasons.

So not the 2x HD 7970 but rather the single card running at 1920x1200 should do the trick.

x-fire or sli are not 100% supported yet in CloD yet = stutters.

Flanker35M is getting HD 7970 soon check out his review when he does it.

gtx 580 3 GB is not bad too. See others reports.

The problem is, you can´t just go into a store and purchase away. The card has to be certified for use with MACs, as it needs a special chip to be accepted by MAC OS.

Hi cheese!

I've got the latest iMac too but went for the i5 and 2GB vram.
I've tested everything (I mean it).
In short, the res on the iMac is what's stopping you from getting hi fps on hi settings. Problem is that if you go with a lower res then, in my eyes, it looks crap.
Not like you can buy a new gcard and swap. Forget that route. You're stuck with what you have. Only upping available is RAM and that doesn't do anything to fps (I went from 4 to 12 without a single frame gained).

But don't be put down. You can make this game look gorgeous. You just have some tweaking to do...and some waiting for the promised ">50% more fps" patch due any year now. ;-)

I'll get back with my settings and other tweaks later. Got a kid that needs attention.

Btw, I soft overclocked my card but that's just for seniors. The iMac is fast to overheat.
I'll tell you more later.

It is possible to run the game in window mode at acceptable resolution. 20" window is enough to play. I would try 1400x1400 window to be able to see instrument panel.

If the new card is adopted for new 2012 series macs then there could be a chance for 2011 series support? I won't get my hopes up, I know it's unlikely.

Not sure what you're asking but changing the graphicscard on an iMac is only for pro...and it will cancel your warrenty plus the extra power will generate more heat and might mess your iMac up.
Also remember that the graphicscards fitted in the iMacs are the mobility type thus lower performance compared to regular ones.

What you got is what you got. But when we get the next patch with the remedelled 3D engine then both u and I will be able to fly with decent frames.
Until then you have to fly with low/med settings and tweak the system.

Overclocking gave me 10 more frames but I can almost hear the mac squeeking from the heat. There are safe overclocks where u might get 5 more frames but you might as well wait for the patch.
