Massive FPS Drop on High Spec Rig ?

[mZLY]

Hi guys,

I purchased Amnesia recently, installed and loaded it up to find I was getting 15-20 FPS. I put it down to poor optimisation as it's an indie game and just continued playing. I got bored quite quickly due to the dire performance and closed the game.

This evening I thought I'd give the game another chance and loaded it up to find I was getting a steady 60 FPS this time. Success! The game looks great and I'm enjoying playing now...

Continued playing for 2 or 3 minutes until I picked up a note, the character read it and when the game resumed I had 15 FPS again. What's up with that?!

It isn't an overheat issue, my temps are fine and there was no gradual slowdown, it was literally a solid 60 FPS 1 minute, 15 the next. Drivers are up to date and my system isn't struggling with the game in the slightest. Anyone got any ideas?? :S

System specs...
i7 870 @ 3.6Ghz
8Gb RAM
Gigabyte HD 6970 2Gb (overclocked slightly)

Playing on max settings, 1080p but really shouldn't be having problems. I play everything on max settings, 1080p.

I COULD BE WRONG, but would overclocking have anything to do with it? Have you tried turning the overclock off?

[mZLY]

The only problem I've ever had in the past with overclocking is slight graphical/colour distortion if it's set too high (which it isn't right now), never lost frames because of it.

Will try again with stock settings and edit this post, thanks for your input.

Edit...

My system crashed completely when I got to the next part with speech, that must be what's causing it. The first time I was running slow from the get-go because of the intro, the second time it was when I read the letter and just now I crashed completely.

Ever heard anything like this before? :S

Is the graphics card factory overclocked? Did you recently obtain the graphics card? Do you experience issues with other graphically intensive games?

[mZLY]

No, it's overclocked through Catalyst Control Centre. Have reset it to factory clock speeds and the problem persists though.

I've had it for over a year with no problems now.

No, it runs Crysis 2 (max settings), Battlefield 3 (max settings) and ArmA 2/DayZ mod (high settings) without issue.

The fact that reading a letter (probably the least GPU intensive part of the game) caused the FPS drop makes me think the problem is not with my graphics card.

as it's an indie game
It is not it has its own engine.
By setting it to max do you mean you maxed out SSAO settings?
Is this system new as your card might be an unlocked 6950 which became instable over time.
Just my 2 cents
You also claim the temps are good how good is good sub 90's is fine higher isn't good.
How is your power supply is it stable?

Driver sweeper and new beta drivers might resolve it

But as this is a OpenGL title it might be something else.
Can you tell us what the vram usage is once you read the note?

Indie refers to the independant developers, nothing to do with the engine. Minecraft is an indie game with it's own engine. :S

Anyway, let's not split hairs...

Yes, everything is maxed. My temps were below 60C, I checked right after quitting out the second time.

PSU is an Antec 750w, yes it's stable.

I've checked for new drivers, there aren't any, I'm up to date.

I will try Driver Sweeper though, thanks!

Poor FPS means corrupted files. From where did you purchase it? Attach HPL.log as said in the troubleshooting guide, Problem X.

[mZLY]

It's from Steam, I've verified game cache twice so I don't think it is a problem with my files but what they hey... I'll attach the log here.

[plutomaniac]

did you exit the game normally last time? The log is not complete.
