How do i set up my 5770 to work properly

Just ran a test on COD, full settings, windowed mode, and keep on watching my 5770 usage log. to my surprise it was only using 33% of it, sometimes toping 60%, and to my amaze i was getting the stuters at 10% memory. i always tought i got stutters when i ran out of mem.

I saw a video on youtube ( wich i could find, it was from a PC pilot guy flying a month), explaining how to fix this, but lost it.... ideas??

Sorry mate, I don't have any answers, but thanks for posting this because I'm interested myself.

I've also noticed that using ati overdrive to clock the card at 950/1425 makes no difference either.
This is with or without ubi logo, with aero on or aero off.
Also changing settings in CCC make only a slight difference to frame rates.

Maybe Luthiers last update with a reference to installing an Nvidia card was a subtle plug to get us all to change.

Cheers! :)

Step down texture setting to "HIGH" or "MEDIUM". No more stutters. Don't get stuck to some numbers, because ALL software we use today don't fully load our hardware, unfortunatelly... :(

ubi logo off.

settings on medium low is what i use to "play" (read try).

thanks for the help, keep it coming

thsi was a test. i tested full graphics to see wath gets streesed out.

game uses 1 gb ram out of the 3 available, fully uses 1 cpu, leaving 3 looking at the air, and VGA at 33%

Were you read this number? In MSI Afterburner here I see that i'm using all my VRAM and my VGA is fully loaded... Maybe just another "benchmark test" that don't work well... All stutters here are related with texture streaming. All of them. I tested a lot! All sliders up, even SSAO, don't lead to any stutter, just regular drop in FPS. The ONLY setting that lead to this behaviour is texture quality. And in all tests I made, my VRAM is fully used by game engine.

MAYBE can be something VGA specific or just an error in test software, I don't know. What I can probably assure now is that texture streaming is the "bad guy" related to stutters.

i have no ideia waht MSI Afterbunner is.

im using task manager and CCC control panel.

Think you're right there, I only see the primary CPU max out while the other 3 never peak higher than around 30%. GPU is always 100% though for my 5770. The ATI/Ubi logo clock speed has been fixed for quite a while I think, I don't see it anymore and haven't for some time.

Lobi is right that it is the texture streaming that causes stutters - but I think it's a case of poor CPU utilisation. During those stutters (and at game load), hard faults go through the roof as textures are loaded into the memory from the HD - some of the texture files are enormous and not very well optimised. If load were distributed more evenly between cores (instead of 100/30/30/30) we might see a decrease in stutters.

For the love of god don't run it on Medium textures unless you have no other choice, it looks terrible ;)

and how do you kick it performance wise?? im unable to goover a stable 20 fps, and i have stutters all the time. My issues are indeed with the textures: each notch lower gives me around 5 fps, and shadows.... the problem is no shadows maeks the game look too ugly :(

All times are GMT. The time now is 07:48 PM.
