ATI 6870 not overclocking (Low FPS)

[Driftit]

Thanks for the info. But I don't seem to have this option which is a pain. Will figure it out.

You have CCC installed don't you?

Is it running in the tool bar?



If so, right click it and select ati radeon than 3d settings and force maximum clocks.

look at my sig to see my system specs...i am running everything at MAX in this 4x4 battle...mind you it is mostly over water and when i flew over the city at treetop level (not in vid) it dropped to 11-15 fps but it should give you a good reference point

BTW i joined a DF server tonight and was getting 80-120 fps at low to medium settings it was ugly as hell but fluid

I can confirm this as an issue. I noticed immediately that performance on my crossfired 6950's was abysmal, even on medium settings, and that even with the Epilepsy filter disabled, the secondary card does not throttle up at all (i.e. Crossfire is completely non functional) while the primary card also runs at only 500MHz (instead of the usual 800MHz).

If you want to check your own cards, use GPUz from TechPowerUp. Just run it in the background, with the Sensors tab selected (make sure to tick the box for continuing to refresh the screen while it's running in the background) and then alt tab out to see what speeds it's been running at. Ignore the current speed though, that will generally drop when you alt tab, instead mouse over the red bar for the GPU Core Clock and the value it displays will be the one it was running at. If you have a second monitor though, naturally you can keep the window visible in that while you play.

I have a heavily overclocked i7 930, a pair of 2GB 6950's and 6GB of RAM, yet the game runs more poorly than Crysis did on my old Core 2 Duo/8800GT. Something is very wrong here.

S!

Noticed same on my 6970HD. Core clocks do not go to full, but to 500MHz instead of 880MHz. Memory clocks go to 1375MHz as should. Also noted better image quality with AF overridden with CCC, some artifacts went away with this. I use latest 11.3 WHQL drivers.

I don't have a maximum clocks, and I'm not sure how to tell if its stepping up or down.
I have a pair of 4850's in crossfire, but they are not both working in this game, the splash logo comes on in other games but not this one.

I did go into CCC and allowed the auto tune to OC it.

If you can explain I'll check what you ask.

S!

I left CCC open and alt/tab to check clocks during game. They did not go higher than 500MHz. I overclocked the card but still the same?!

Also these black cursors people talk about are gone for me. I closed all the info windows, could that do it? Also overriding AF in CCC helped with graphical artifacts.

I tested Very High settings and got 11-38FPS over sea/land. Lowering to High helped a bit, but there is a lot of pauses and stutter. When these issues are solved the game will look simply gorgeous

I have a second monitor and have the CCC open when in game for monitoring.

The setting for force maximum clocks is only in the ati tray bar. right click, select your top card (either one will work) than 3D settings and than force maximum clocks/enable

If that does not force one of your cards to ramp up to 3D speed than you will need to disable one of your cards.

only a attempt to help,...but did you delete the ubi logo file??may this helps
