Yeah, no difference.

Will pushing it to 3.5 real quick by an indicator of anything? I'm wary of pushing it to the 4ghz range on air, but I should be getting a WC setup in a few months or so. I wouldn't expect too much though, as 2.9->3.3 only gave me 3fps.

lol. it is a step in the right direction! However, does this mean that my CPU is the bottleneck when I crank the settings back up? What else would explain the lack of difference between 1/2/3 GPUs? Further, if that is the case, why did I only gain 3fps when bumping the CPU from 2.9 to 3.3? If I was that starved for CPU power, shouldn't a slight OC result in significant frames? For example, the same OC gained me an additional 8fps in the Just Cause 2 benchmark (concrete jungle), but the game itself already runs at absurdly high fps.

Just with it enabled. I'll disable and run it again. ---------- Post added at 02:52 PM ---------- Previous post was at 02:45 PM ---------- Ok, with SLI disabled that time I got 41fps with the same settings (2080ish visibility [couldn't select 2036 again, lol], low object and terrain detail, everything else very high, 120% 3D).

I just did that... I'll try again now. ---------- Post added at 02:38 PM ---------- Previous post was at 02:27 PM ---------- No difference, again. I know messing with the settings will give me better performance, but I'm trying to figure out why SLI is bugged. Even if tweaking settings results in better fps, it doesn't explain why disabling SLI entirely gives me 2 extra fps with identical settings. That alone says that something definitely isn't right.

Ok, I just switched the settings Terrain Detail : Low, ... Objects Detail: Low 3D resolution: 120% , Visibility: 2036 Benchmark 01 result: 61fps avg Everything else was on Very High.

I just ran Benchmark 02 with Tri-SLI and got 16fps... this is awful. Here is a pic of my CPU usage, it looks a bit odd:

Run the benchmark with those settings?

This is really frustrating. Here is a pic of the GPU usage with SLI disabled (compare it to the earlier picture) while running the benchmark. I got 36fps. ---------- Post added at 01:28 PM ---------- Previous post was at 01:25 PM ---------- Here's another thread where a guy tested it with SLI 580s and look at how his charts compare to mine: http://www.evga.com/forums/tm.aspx?high=&m=986122&mpage=1#986698 His look very similar when in SLI or with SLI disabled, while mine look similar to his with SLI disabled, yet look much different with SLI enabled. ---------- Post added at 01:37 PM ---------- Previous post was at 01:28 PM ---------- Is there any way that you could drop your resolution to mine temporarily and put everything on Very High and test again? Visibility at the default. I just want something to compare to.

We are talking about the same benchmark, right? The one with the lumberjack in the forest?

What if you disable SLI?

What cards do you have? And what is your average FPS in Benchmark 01 with my settings?

I wonder what is causing it though? Even on that GPU usage pic I showed, the % used is very close for all 3 cards (matching peaks and valleys), and it never goes above 70%, even on GPU1. It's like the game is spreading the load evenly to all 3 cards, yet only giving the performance that would be seen out of one card. ---------- Post added at 03:32 AM ---------- Previous post was at 03:27 AM ---------- I found this link while messing around on google, it appears he has the same problem as me but with an ATI card: http://forums.amd.com/game/messageview.cfm?catid=260&threadid=125624

I did that, and got the same result. High 40s/low50s, but it jumped really high when looking at the sky (as expected). However, the benchmark only went to 36fps, and I'm guessing the 2fps jump is due to the frames greater than 60 at the beginning (had 70-80 for a few seconds, they were probably previously locked at 60 due to vsync).

By away from the base, did you mean just around some trees? There weren't any structures around other than trees and bushes and I was getting high 40s-low 50s with Tri-SLI. However, I did notice one thing that may be odd. The FPS never went above 60, which makes me think VSYNC is enabled, but I couldn't find an option to disable it in the settings. It never went above 60 even at the main menu, or when looking at the sky (would jump to 60, but would not go over). I know in others games VSYNC has caused issues, so maybe it is doing it here too?
