Weird performance issues in Crysis

[orangeble]

Ok, I downloaded the Crysis benchmark tool, and so far everything has been fine, but I have 2 weird issues that seem to come up:

1) Whenever I do a benchmark with 3 loops, the 2nd and 3rd runs run at about 1/2 the fps as the 1st loop, so if I'm averaging around 30fps with the first run through, the 2nd and 3rd get around 15-20fps. It just seems strange. Ingame, the performance always mirrows the 1st test so I can't figure out what causes the performance hits in the repeat tests.

2) I tried messing around with the settings and resolutions, and decided to see how good the game would perform at 720p with very high settings enabled. To my surprise, it performed very well with an average of 30-35fps. But then when I tried to increase the aa to 2xaa to compensate for the blurriness of 720p, my performance droped all the way down to 10fps. I have a 9800gtx with 512mb vram, so I think that the low ram is what's causing problems with aa (though aa in other games works great). Any ideas?

Have no idea what's going on with (1), but (2) is just a sorry fact about Crysis itself. The only card I would want to try running AA on at that res with that game would be either the one I have in my sig or the 8800GTX / Ultra. I can't play Crysis with AA either, although I do play @ 1920x1200.

Yeah, I figured the old 8800GTX would handle the aa better thanks to its higher vram. I typically play at 1920x1200 and wouldn't even dream of turning on aa otherwise my card would just quit out on me, but I thought that it might have worked at 720p resolution. Oh well, the game still looks great even without aa.

9800GTX has plenty of Vram, its just not fast enough. You'll see a pretty impressive return from a memory OC. 70GB/s (256bit @ 1.1GHz, ie 9800GTX) is a little on the weak side for todays Video card's. The GTX280 and HD4870 have twice that, 140.1GB/s and 120GB/s respectivly.

As for problem 1, is the 3rd test worse than the 2nd one? and what happens if you run 1 loop, close the program, restart, and run another. Same anomaly?

Well, yes, but if we go that route, I could just run Crysis on my gameboy. I would only need to overclock that z80 core and its memory well past the temperature of the sun.

Nope the 3rd and 2nd tests are the same and it only occurs if I run a multi-loop benchmark. If I run 2 single loop benchmarks in succession I don't have any problems.

I also have the vram running at 2400mhz through the eVGA precison program, so its already oced.
