SPOILER ALERT (Well, not really but someone will probably complain).


I've just reached the scene where I have to save Pavel and am crawling through the air ducts, and my FPS has dropped well under 10 Avg. Even when I get out of the ducts, the fps remains below 10.

I've tried setting my resolution lower, no anti-aliasing, lowest AF, lowering over all quality, turning off tessellation. None of these make a difference, any ideas?
 
Always forget to put my spec into the sig, they're briefly as follows:

- I7 3820
- 8GB Corsair XMS3 1600Mhz
- 2x 7970's @ 1100/1600
- Asus Rampage IV Extreme
- Corsair AX1200 PSU

Try to disable one 7970. To see if it affects performance, because there are some frame time problems with AMD Radeon
 
What's "frame time problems"? I should note that this issue is only with Metro Last Light. Titles such as Tomb Raider are playing perfectly fine flat out, so is Metro except for when I've reached this point in the campaign.
 
There's a thread on the steam forums to report issues 7 I've seen a few people with a similar problem. Doesn't seem to be fix yet.
 
I remember this bit. At the end it was crazy low fps, with lights shining down on a certain event? Anyway, make sure SSAA is off, I found that's what killed my fps. Seeing as you said you already have though, have you tried going further? Apart from that bit it was fine for me otherwise (especially, as I said, I turned SSAA off).

Goes without saying too, drivers up to date I assume?
 
This won't be the frametime problem as that just makes it feel less smooth than the displayed framerate rather than resulting in low framerates.
 
I've seen a few threads on various forums too. Hopefully this is a driver/engine issue and we can get a fix before long.

All my drivers are up to date, I had to switch from the 12.9's (iirc) to the latest 13.4 in order to play Tomb Raider without her huge rack going nuts. I'll play out Tomb Raider and hope for a patch in the mean time, if not sub 10fps gaming it is :D

I'll delve into the config files for Metro and see if I can strip off any post effects all together seen as the ingame menu seems to outright lie; AA is still visible when supposedly off.
 
sounds like framerate times as someone just mentioned there was a benchmark recently for the 780 gtx which showed how bad many recent games are with certain cards. some of the high end nvidia cards were very bad for this and sli or crossfire configurations.
 
So whilst messing with settings I've found a "solution" if I can even call it that. For some reason playing at 1920x1600 with everything MAXED (AF, AA the works) the games runs buttery smooth with a solid 60fps under Vysnc.

I was wondering if this was a resource issue like BF3 had at higher resolutions, which required well over 3GB (effective, 6GB XFIRE)) VRAM to run even without AF or AA. However the Afterburner screen output shows the game barely hits 1.6GB (effective, 3.2GB XFIRE). My RAM usage also only reaches 5.4GB, with the desktop idle of 2.12GB. CPU usage also peaks at around 80%, so I don't think there is a bottleneck but I could be wrong.

I'm fairly sure this is a driver/engine issue to do with higher resolutions, given the number of times this game simply crashes with no explanation I'm convinces this is the likeliest explanation. Unfortunately it probably means waiting weeks, or months for AMD or 4A to get a shifty on with a patch or driver update. Man, sometimes I wish I stuck with Nvidia, no fan boy **** they simply release drivers quicker :D

Do you use Radeon pro? Check out the users guide on these forums to smooth out any problems you may have with crossfire.
