graphics bugs with ATI 4800 series (4850/4870/4890)

[Von_Paulus]

Hope you don't mind me commenting in this thread. I have a sapphire 4870 HD and noticed you were talking about temperetures early in the thread. Just standing my GPU is at 63 degrees celsius so god knows how high it gets when playing. Do you think increasing fan speed could improve game performance for me?

Core 2 e8200 2.66ghz, 2GB Pny Ram, 1GB saphire 4870HD

running the game on windows 7

thanks

Try to use GPU-Z when playing and see what temperatures you get.

Around 70º, I think, it's natural with your video card. I've a 4890 63/65º is what I get when pushing.
But don't expect improve game performance. Low temperatures will improve your card's life and stability.

New 9.7 Catalyst drivers (beta) have had a beneficial effect on the 'locked' FPS (at 60). I now find that with these drivers I can get a whopping 225FPS when looking at the sky.

Will do a test flying over Chernogorsk at low level to see if there GFX tearing occurs as much. Even if it does I think they are worth getting.

EDIT : Nope the tearing STILL occurs when flying low over Chernogorsk. Is it the rate of transfer of textures that is causing the problem or the size of those textures ?

If you don't want tearing then you need to have vsync on, that way your FPS will be 'locked' to your maximum refresh rate (60 is you are using LCD normally). Maybe you are getting confused as to the issue here in this thread ? This one is about graphical corruption not vsync problems. No offense.

Can somebody suggest why my framerate dips everytime textures load?

I've got an i7 920, 6GB of ram and a 512mb 4870, yet for some reason the game doesn't want to load the textures smoothly on the fly.

When approaching a city for example, I get quite a bit of stuttering until everything is loaded.

Engine problem, how much graphical corruption or bugs are you getting ?

Not too much, nothing that's jumping out at me anyway.

Pretty much the only issue I have with the game is my framerate dropping while objects load.

It's stupid how I have 6GB of DDR3 which is hardly being utilised, yet I get loading problems...

Used the wrong terminology. It's not tearing (and therefore a vsync problem) is complete GFX corruption.

It seems to happen when lots of textures are to be loaded at the same time. The GFX card can't handle it.

this worked for me and made the game playable again (25-30ish fps)after having all the same probs as everyone else....i`m running an e8400@3.6ghz 4870x2 4gb ram xp sp3....check your virtual ram/page file settings and if possible move it to another hard drive and see what windows thinks your system managed size should be(mine was 6gigs!)the more the better and set it to that,restart computer,then start the game with low to normal settings and crank them up until your fps start to drop,the artifacts stopped appearing and the game stopped crashing for me.
hope this helps.
