Why GFX card with more RAM?

[Chivas]

I have less than 3 gigs of vram and have never had a CTD, or Launcher exe problem, or frame rate issue. It tells me the code isn't all bad, but an optimization/rewrite of the code it still urgently required. Hopefully the next patch will fix most of the performance issues, and the developers can put more resources in fixing the game play issues.

You are lucky or you have a lot turned down. I have nearly the same rig as you with more ram and 2x gtx 580 3 gb and it stutters and looks bad with no AA or AF even with decent fps. CoD uses way more video ram than you have so you must have it turned way down or fly over water all the time. It uses upwards of 2.5 gb vram and I have a few things turned down and that is with no AA or AF remember. Turn those on and it would be a slide show for everyone, that's for sure. That is proof of a need for optimization. I look forward to the next patch and stutter free flying.


I also have had a couple of CTD's and the launcher doesn't respond sometimes when you change settings and it reboots the game. BTW, why does the game have to restart whenever you change video settings?

EDIT: "On the other hand, locating a memory leak can take many long months of dedicated work by some extremely qualified programmers." -Luthier today. There well may be memory leaks which I had suspected.

I have everything turned ON and set to HIGH and run @1920-1080. I only installed one 580 until the sim is optimized to run with two. I think the main reason I have no problems as I have the sim installed on a separate SSD, with only a copy of Windows 7 64 bit, and peripherals installed on it. The game loads, missions start in a few seconds, and never CTD's. I also have a very fast 50mbps online connection. A 60gig SSD is relatively cheap, but I have to reboot to its Operating System when I want to fly COD, although the reboot is very quick. I also have COD installed on a HHD with Windows XP, and its excruciatingly slow in comparison.

It must be the SSD. I have W7 on an SSD and CoD on a Velociraptor. Perhaps I should install it on my SSD. That would explain the stuttering at good fps. I'll let you know if it makes a difference.

Edit: $%#%^$# Steam won't let me put it on my SSD C drive and I'm not going to dual boot on a separate SSD. For me, sooo not worth the hassle. I'll wait for the patch. If that doesn't fix it, I'm shelving it for good. Thanks for the reply though.

Hmmm... Steam was able to install COD on three seperate harddrives 2 HHD's and one SSD on my system. One with XP, and two others with windows 7. Can you copy and paste Steam and IC Softclub onto your SSD, and try running it from there?

No, my Steam account is bigger than the remaining space on my SSD I need two instances of Steam and that is a no go.

I can't say an SSD will solve all of your CloD problems but it sure loaded faster and ran smoother on my SSD. Harddrives are so over the top expensive right now so why not go for one?

SLI or antivirus shields or power settings or something else can be a reason for stutters in your case. Look through my checklist in link #8 in my sig for possible reasons. Freycinet videos show that the game runs great on a single 580 http://www.flightsimvids.com/

I agree, something else in play. I do not suffer those conditions with my 2 gb...may I also suggest to make sure your system is on a scheduled defragmentation.

@ icarus...not sure of your system because not listed in your sig. If Win 7, try running Windows Experience Index..right click computer/properties/windows experience index

What setting do you have Textures at? I have a 570, and see lots of stutters at 'original' setting (uncompressed textures), and some stuttering on High. It pretty much completely goes away at Medium (occasional stutter when going over new terrain down low as the textures swap out).

With the current state of the graphics engine being a coding mess of temporary patches over poorly executed original code there could be any number of reasons for hitching, but the classic one is waiting for textures to swap in and out of video memory. This seems to be supported here as SSDs reduce (but do not eliminate) the symptoms. I don't see hardly any difference at 1900x1200 between Medium and Original texures when actually flying the sim, but the performance difference is huge. Reduce the amount of data swapping in and out of VRAM and you reduce stutters.

Hopefully the graphics engine overhaul will put this to bed once and for all at medium-high settings.
