Installed new GTX 770, Metro Last Light getting horrid FPS during intro gun-range area...

(Technically this post has spoilers for the first 20 minutes of the game)

Hello there, I just got a new video card to replace my old 560ti. Here's my system:

Core i5-2500k
ASRock Z75 pro3
8gb G.skill DDR3 1600 ram
Antec 80 certified 620w PSU
Kingston 120gb SSD
EVGA SC GTX 770 ACX 2gb.

So I loaded up Metro Last Light for the first time, as I wanted to christen my new 770 properly. Fired up the game in 1080p with "very high" settings and SSAA set to 2x; I was delighted at the incredible visuals during the opening scene where you're in the tunnel with 3-4 dudes and you get set upon by those freaky monsters...you appear to hallucinate and wind up killing your squad and stabbing the last dude in the neck as they phase in and out with monster bodies. At this point....game looked stunning and smooth as I expected with this card. Then things got weird.

The next part of the game starts up where you are in a station/base and you meet that dude who gives you your first items and weapon loadout; he then instructs you to try out the firing range. During this entire area, the game bogged down to 15fps, even after lowering the settings to "high" and turning off ssaa & tessellation; I also set textures to normal - still 15 frames/sec. I was horrified...I thought the 770 was supposed to be fairly gnarly? I slogged on until I had to follow the snarky sniper chick to the train. With the ride on the train and the next area, everything was back to smooth, silky goodness. I ratcheted the settings back up, and it was smooth sailing, back to 60-80fps. Got to the surface, had an intense fire-fight with a bunch of mobs, and interfaced with the baby dark-one. Totally smooth and ran as I expected this card to.

The card is running VERY cool...idles at 25-29c, never got above 65 under load. The minimum recommended PSU for the GTX 770 is a 600w, so I should be ok there.

Has anyone else encountered this? Is that part of the game like super un-optimized or something? Could something be wrong with my card?

note: Afterwards, I ran BioShock Infinite totally maxed and got like 90-100 fps. Stunning perfection.

tl;dr: Got new GTX 770. Fire up Metro, looks amazing at first; get to area where you get your first weapons, game runs unplayable at 15fps on medium-ish settings, get to train, everything smooth and creamy again, able to crank settings back up, still smooth. Unsure why.

  1. metro can be very hard on cpus. is your 2500k overclocked?

    No, I'm running the stock fan for it, so I have not attempted to overclock it. Can my cpu be overclocked running the stock fan? It just seems so weird that the one area of the game ran so poorly.
  3. yeah. an i5-2500k can be overclocked with a stock fan. I'd try that before i start to think the gpu is faulty. see if you can't get the cpu up to 4.0ghz or so... and then tell us how the fps are in those areas.

    I suspect your problem is your cpu, metro is brutal on cpus, and generally when they bench metro, they use overclocked intel cpus, which can hide problems like this. That 2500k is a beastly overclocker, give it a shot and see how high you can get it. i suspect it will hit close to 4.5ghz on that stock fan.

    Hey, sounds good. While I've built rigs and swapped quite a few video cards, I have to sheepishly admit that I've never overclocked a cpu before. If I can do it safely with a stock fan, I'll definitely try it out. May as well use my cpu's full potential! I'll make sure to do my homework and do the overclocking incrementally so I don't wind up frying my cpu. Thanks!
  5. BTW, can you point me in the direction of a tutorial where I can learn to overclock my cpu? I've been trying to search, and I'm not having much luck.

    I can give you a basic rundown.

    1) First you'll have to ID the chipset on your motherboard. if it's a "z"+(some 2 digit number) motherboard you'll be able to overclock that cpu. (like z77, or z68)

    2) go into your bios, i don't know what your motherboard is, so these instructions will be a little general, so you might have to figure a little bit of this out on your own.

    3) go to the "advanced" settings or "main settings"

    4) change from automatic to manual.

    5) change the cpu multiplier from automatic to manual. on the 2500k, the base cpu multiplier will be x33 which makes a cpu frequency of 3.3ghz (cpu frequency 100mhz x 33 cpu multiplier = 3300mhz or 3.3ghz). Bump it up +1 (3.4ghz)

    6) go down to the voltage control, look for vcore. change it from automatic to manual. leave it at whatever voltage it is currently (all cpus differ a little on their stock vcore)

    7) save and exit the bios, your computer will restart. let it load into windows. Assuming it loads into windows without any issues, reset the computer and log back into the bios, bump the cpu multiplier by +1, rince and repeate. Continue bumping and loading into windows until the computer starts to behave strangely, crashing when loading windows, getting sluggish or odd, programs not loading, or failing to post. If any of this starts to happen back the overclock down one step and dl two programs, one is prime95 the other hwmonitor. Turn on hardware monitor and then let prime95 run. If prime crashes or a core fails or your computer crashes, you don't have enough voltage. Bump the vcore 1 step (this depends on the motherboard but it should be something close to +0.0125V), save and retry prime. If prime can run for 10-20 minutes and temps don't get over 85C on the cpu, you can continue to increase the cpu multiplier, only from this point on, you'll need to test each bump in multiplier with prime95.

    8) once temps become an issue you've hit the end of your overclocking. back the overclock down to the last good version, and run an extended prime95 burn (12 hours or so). if it passes then your overclock is stable.

    ~this is a quick and dirty, there are more things you can do, but this is the basics. its a good thing to do with a lazy afternoon. takes a lot of trial and error, but overall can give you some rather nice results.
  7. Do you have advanced physx enabled? It should be in the game options menu. That was the cause for me on my 780ti. Turning it off fixes fps. There is a way to fix this. If you go the nvidia website go to drivers and download the latest physx drivers it should fix it and you should be able to play with the advance physx on. Well this method fixed it for me fingers crossed it fixes it for you.
