Game Benchmark: Crysis
To demonstrate a memory usage difference in Crysis, we're going to benchmark first with the High quality setting and next with the Very High quality setting. The Very High settings will use higher-resolution textures, increased shadow resolution, and advanced post-processing that might demonstrate a difference using three levels of texture memory:
First, the High settings:
Only at the high 2560x1600 resolution is the 512MB card experiencing a slight performance penalty. Let's see what happens when we up the ante to the Very High quality settings:
Once again, there is no difference in average frame rates until the 2560x1600 resolution, but the game is running so slow at this point that the results are purely theoretical. However, if we look closer we can see that the minimum frame rate is consistently lower on the 512MB card, so the increased amount of video RAM is providing a benefit.
Crysis remains one of the most performance-adverse PC games on the market. The fact that the 512MB card achieves average frame rates similar to the 2GB card at 1920x1200 suggests that Crysis is somewhat conservative with video RAM use for such an advanced graphics engine.

Great article guys. I've debated this many times with friends- good to see a definite result. Heh, GTX 275 w/ 896 works well @ 1680x1050 for me. I doubt I'd need anything higher than that for my resolution.Reply
I really like the alternating images you use in these articles, they are very helpful and make it much easier to compare the various detail settings.Reply
Also, great article overall. Keep up the good work!
Thanks burnley, animated GIFs are a bit of a pain to make, but it's nice to know they're appreciated. :)Reply
This was very interesting. But I would like to see the performance difference from a mid-stream (say a 4850) as compared to a high end video card. Would it have made sense to spring for the 1GB 4850, or would there be no difference because of the cards inherent limitations? And the same thing with the lower level cards. At what point in the hierarchy of video cards does springing for more than the reference memory levels make sense?Reply
With lower end cards you'd see the same effect, but with the lower frame-rates that those cards would produce. The end result is the same: one they run out of RAM at a certain setting, the performance will suffer, but until then it's the same across the board.Reply
How much ram will the 5870 eyefinity version need?Reply
knutjbHow much ram will the 5870 eyefinity version need?Reply
Depends on the resolution and settings just like everything else. but it's a good question, if there's enough interest in this article I'll look into that in the future.
Im surprised that Crysis doesnt utilize all the RAM(even for an older title) for distance similarly to titles like GTA. Im sure the new Crytek engine will make use of Ram so we can see even buildings and huge alien robots further in the distance with vivid details.Reply
We can only look forward to a more intense and visually stunning Crysis 2 as I can only imagine how the story would progress and end up being in space. I can imagine huge asteroids looking as real coming at the player using nvidias 3d vision and utilizing AA in order to make it apparent from a distance.
Think Halo style world but with unrivaled graphics and a more realistic feel with DX11.
How about doing this same comparison with crossfire setups?Reply
il tell ya whats a bitch, i have a 1920x1080 monitor, nice? yes. I have an 8800GT too.. nice? kinda.. its the 256MB version.. so.. if i wanna turn up the sexiness i get baaaad fpsReply
