Thanks for bringing this one up again, I have broadly similar specs to you and have been almost unable to run cod. I tried the new patch and it made a small but positive difference, but with this aswell I can almost max out my settings!

Low level is problematical still but still vastly better than before, the only problem is the ctds. I am now getting a lot where I had none before.

Not sure which I prefer tbh: a broken game that chugged along, almost totally unplayable, or a semi-fixed game that crashes every 10mins!

This tweak must of been what gave me a big fps boost as well :)

I did this this tweak when I updated my ati drivers to 12.4 and I thought the update gave me the boost :)

Nice to know if i did a reinstall thanks :D

This is a great little find, just applied said fix and my FPS went from around 25-30 to something around 50-80. Has made an unreal difference.

I must be one of the lucky ones as I have never experienced CTD bug at all, game is good to play in general. Biggest let down is the AI!!

I thought my pc was ageing, however I could play nearly all other games on max settings DCS a10 for one. Never occured to me that because of the intro my gfx may have been on idle speed of 300mhz compared to full throttle speed of 760mhz.

One happy camper:-)

Did it really have influence on the real gameplay? I just thought, that the video intro just caused problem in the fps of replays!?! But when I am thinking about it, it should also effect the game itself logically.

That is a known bug, where the video card do not speed up, because it thinks, that the whole game is a video/movie. So some ati cards just speed up to a "movie watching preset clock"!

First thing, that I nnoticed with my new hd7970 was, that it just speeds up from desktop or 2D mode to something around 500 MHz core clock,, although this card is normally running above 1 GHz.

I found out with msi afterburner and its ingame overlay.

It is good, that u mentioned it again for all new guys. The topic is "not good" and I initially wanted to suggest to close another senseless thread next to others, where people already complaining. So, there is no need for a personal complaing thread. Perhaps someone close this and put this tipp into a more suitable thread. - Your decision

It stays in 2d mode because we still dont have proper full screen, fly then press escape key, if you see your desktop then its not in fullscreen. Fullscreen forces 3d mode, to see your desktop (2d) flashing at you means that its flicking between 2d and 3d lots and that its REAL unhealthy for your GPU.

Really? Why?

S!

I recall the UDV feature in AMD cards locked clocks to 300MHz or so as above that UDV does not work properly. And this is for video things. Basically it could be that the video makes the card run at 300MHz but for some reason does not recognize the 3D mode coming after that. So disabling the intro movie helps you to keep full clocks.

Another trick to make clocks go up(tested ages ago with 6970HD) was to overclock your card for example with a mere 5MHz and it ran full speed. Sometimes had this phenomenon that card was running at arounf half MHz in game. OC helped with this.

I do not think we have a real full screen yet. In other games I do not have this where the desktop flashes upon starting a game, in CoD I can see the start menu button etc. briefly when the game loads.

But anyways tips for better performance with AMD cards: disable Intro.vmw and OC your card just a little bit. At least the intor thingy will help.

And i see Skype blinking right lower corner when someone is coming online when flying, so i think there is some problems in fullscreenmode.

To fix the red square loading icon, run the game in pseudo mode. This will also make switching from game to menu (in multiplayer for example) much, much faster. Particularly if you have a slower CPU.

I have seen a decent increase in fps as well, however the fps still tanks down to 10 or under sometimes when flying low with other planes around, like a slide show.
