Metro Last Light and HD 7870

This game is a real hog. When playing on high no AA i get around 50 FPS but then it drops to 17 FPS for about 30 secs and becomes a slide show. Is this normal or is this game just demanding. Using a HD 7870 1200/1450 AMD CCC 13.3

only with SSAA does it get super demanding

Yep. It's a highly scalable engine with a lot of the problems with the original 4A engine implemented in Metro: 2033 fixed. I was a harsh critic of the 4A engine in 2033, but it's great in Last Light. Anyway, you can easily adjust a few settings to make it workable on a wide variety of configurations. Honestly. I've experimented with lowering settings in crysis 3 and Metro:LL by 1-2 notches and in actual game play I can't notice a difference really. The changes in visual quality with High vs Very high in crysis 3, in particular, are non existent - it looks like the very same game. But the framerate goes up a *ton*.

I'm excluding SSAA from the above, because obviously SSAA will always look better than FXAA or MSAA - but the performance hit is outrageous. I can't think of any game, aside from very old ones, that are remotely usable with SSAA (I play at 1600p.).

Well you didn't provide proper context in your first post. If you had told us what quality setting you're using, maybe someone could better help - you can't get help if you don't provide enough information/context.

I feel like you would be fine using the medium quality setting. If you're playing on very high, I would say no joke you would have framerate issues. It is very demanding on the highest video setting.
 
l4et me guess - low gpu usage on fps drops.
my guess its your CPU not GPU. Ive seen FX behaving badly in Metro LL.

if not, watch your gpu clock for drops
 
PhysX.

Run the benchmark. It's an exe file in the main game folder. I ran the benchmark with the same settings as I play with. Everything on and very high, except for SSAA and Motion Blur. The first half of the benchmark runs at 50-60 fps. During the 2nd half of the demo my fps drops to 5-6. The second half has all the explosions and stuff flying around. When I ran the benchmark again, but with PhysX disabled, my framerate stayed above 40 during the 2nd half of the benchmark.

Conclusion: PhysX can bring your machine to its knees.

(FYI, I have a i5-3570K and a gtx680).

OP there was a Metro Last Light game patch recently released which improved performance and stability on HD 7000 cards. So make sure you have the latest game patch installed. also run the latest 13.5 beta 2 drivers. Metro Last Light is very demanding.so choose settings which allow a good playable experience. Disable SSAA. disable physx. use normal tesselation as that setting seems to affect performance a lot.

Not using any Physx as i don't have an Nvidia GPU.

PhysX is enabled by default.
Supposedly, it does something even on AMD videocards. But on the CPU, not on the GPU. So if you haven't actively disabled "Advanced PhysX" in the settings, I would certainly try that. From what I've seen, PhysX is the only thing that could cause suddenly fps-drops during regular gameplay.
 
Tried to run the Benchmark with AMD CCC 13.3 but it wouldn't run so uninstalled them and installed AMD CCC 13.5 Beta 2 and this is what i got on Medium Settings

OP have you updated the game with the latest patch. if you haven't install it.

your performance is lower than expected.

medium settings, motion blur normal, tesselation normal, advanced physx disabled, AF 16x. Scene D6.

HD 7870 scores 58 fps at 1920 x 1200 with higher settings than what you have chosen.

I don't think its my CPU

@raghu78 checking for the update now and also take into account that my GPU is Oc'd at 1200/1450
 
It's an nVidia title... works flawless for the most part if u get the game updates to fix the issues for amd and logitech periphials hardware
also Crysis 3 works perfectly on my 7870 but Crysis 2 does not... why? C2 is nvidia, C3 is amd optimized.

how was the game not already patched after all this time? where you in offline mode? if so then you should have seen the news and all the comments in the forums that a patch was released and updated before now.
 
I just started playing Metro: LL the other day on my 7870, and it runs wonderfully on high settings, 1080p, AA and PhysX turned off. I get over 60fps in most areas. In more intensive areas, it drops to 40fps at worst. I've never had a 17fps "slideshow" as OP describes. Something sounds wrong with his setup.

did you even look through the thread? it looks like his issues have been fixed by finally updating the game. dont look at the minimums of the benchmark as they mean nothing in a flyby bench.

I guess I didn't read it properly, my bad. The topic was posted yesterday, and there were certainly no Metro updates between yesterday and today, so I figured OP was already using the latest version of the game. I guess not.

yeah all I could figure is that he was in offline mode.

Yes i was in offline mode as i don't use steam much and no i have never thought to look and see if there were any new updates for it as after i got it i forgot about it until today when i wanted to record gameplay
 
As a comparison, my Titan at 1920x1200 hits 60-65 average, every setting pushed up excluding SSAA. Turning on SSAA hits 40-45 FPS average. This game runs way better on Nvidia hardware even after the recent AMD patch (looks like). Only slight dips to just under 50 rarely, which I suspect is Adaptive Vsync dropping some frames. Benchmark 57FPS average, and with all the PhysX in the second part I see very brief dips to mid 40's, a second or so.
