Hi Mike,

Most likely what you are seeing is the loading of new objects.
This happens once you get close to a set of objects that where not loaded before as they where to far.

Thanks for the reply. Been playing with some settings and trying to see if there was a pattern or maybe the video driver not liking this version.

Not really sure, but I think, that they played around again with some "level of detail" settings and that the are also influencing the ground objects texture loading.

So, it could already help a bit to get a new ssd drive instead of hdd, if you are still using normal hdd
Otherwise have a look over your ram usage on the graphics car. If it runs out, this could also cause it, bit these are most commonly named "stutters". Just a possibilty as I am not sure, what the difference between stutters and pauses are? The duration? I think, they all have the same probles behind it. -> means: Low vram on card, low hdd speed or low normal ram(which I haven't ever seen in clod.

Still using the old standby HDD. I can tell that the textures load a bit different now. When rolling down the runway for takeoff the grass will render closer and more in the "pop-up" fashion as the building do. Only have a 1.5 gb 580. The pauses sometime will stop the propeller and using the frame counter will bring the LOW to 0. I have adjusted some settings in the Nvidia control panel and have reduced these. SSD and 3 gb card may be in the future...seems the way to go. Didn't realize the HDD would have an effect in game but reading more about it on these forums I see that it does. Thanks again for the replies

Hi Mike

Before you go spending money on new hardware, why not check how much VRAM you are using with your current settings? I use MSI AfterBurner, and was surprised to see how much VRAM CloD needs for various levels of detail – more than 2GB with everything on max. With some settings reduced, my usage varies between 1.20GB and 1.80GB.

I have tested CloD on a couple of machines with different configurations, and found that as soon as the VRAM is exceeded the stutters start, even at fairly high frame rates. With your card you should be able to run quite high settings, just not maximum.

The stutters seen when first loading scenery is normal, but these should reduce once they are cached. If these continue, I would say you’re exceeding your available VRAM.

Tony,

Something I don't understand is that, if the 2Gb VRAM on one card is maxed out, why do I have the same issues with stutters/temporary screen freezes as mentioned here with two cards linked by Crossfire? Effectively 4Gb?

Also, why do we need 16Gb of DDR RAM when only 15% (on average) seems to be used when running the game?

Regards

Hi BJ (sounds vaguely rude )

When running X-Fire you still only have the VRAM available on one card – each frame rendered has to fit into the available VRAM on each card, it isn’t shared. For ‘alternate frame’ rendering, the cards take turns in rendering successive frames, so whatever detail is being rendered is done by one card at a time, taking turns.

And you don’t need 16GB of RAM for any game – most are 32-bit and therefore couldn’t use more than ~3GB, although I have never seen CloD use more than ~1.30GB (even when VRAM usage reaches nearly 2GB). Having more RAM than you need won’t improve performance; it will make your machine a little slower since all the memory will still need to be mapped by the system, even if it is not in use. The actual difference is negligible, though.
