Why GFX card with more RAM?

[FS~Phat]

Here's some more info from Oleg's old ready room.
For those that have never read it, its long but a worthwhile read that gives you some insight into the plans and difficulties in achieving what has been done with CoD.

Here's one of my favourite quotes from one of Olegs responses to questions.

"For us is a great task how to make a lot of details and at the same time to render a lot of aircraft in air simultaniosly.... So all things will be optimized for this...
Say it is possible to make even greater details of damage, aircraft itself , etc... but probably in case of hundreds aircraft in action around you you will need the PC that will be existed only say ten years after release
Hope you all understand what the tasks we have and what the technical problems are on our board...
The is no problem to make increadible amount of polygons in aircraft (or ground units), but then will follow problem of PC power, when in air isn't just one aircraft.... When the water is trasparent, when the clouds looks like real and moving, etc...
BoB will be again a "fight of compromises" in technologies and will offer the best compromises that wioll be usable for many years ahead, like it was with Il-2"

Great post FS_Phat, thanks for keeping and posting those comments and reminding us all of the technical challenges this sim imposed!

One more question, what is the relationship between the GFX card and the CPU with regards 'bottlenecking'? Is this simply a GFX card whose performance outclasses the CPU and thus has to wait for X amount of CPU cycles and seen as stutters, drop in FPS etc and why the use four cores should have a major advantage of say two?

I did not measured but I think that the game on high settings uses more than 1 GB over cities and low altitude terrain (1920x1200), over the channel there no problems on high.

BF3 uses more than 1 GB on high settings over 1920x1080 for example, 1GB is a past thing on high level gaming, today mid range cards packets 1.5 GB usually and top end cards pack even 3 GB on a single GPU as the ATI 7970.

Yes it uses the full 1.5GB in my cards a lot of the time at 1920x1080 with all details on max. Not all the time though, sometimes it hovers around 1.2, 1.3GB.
