These last couple of days ive noticed something weird happening with myfps in games. I was playing crysis and getting 60-80fps @1680x1050 which is fine but when i looked at the graphs on afterburner the gpu usages wasnt constantly up at 98-99% like it is when i play games like dirt2. Also i was playing modern warfare 2 just now and i was getting like 30-40fps @ 5040x1050 and again in after burner my gpus were hovering at like 50 60%. I definately dont have a cpu bottleneck, any suggestions.

Running cat 11.2

Ohhhh this is really what i dont want to hear.

When the next gen comes out i guess ill try and grab 2 6950's when the prices drop and flash them to 6970's :( DAYUMMM.

Is there any program i can use to monitor vram i saw in the high res screen shot thread some person had one which was an overlay like fraps i asked but havent got a reply yet...
 
apparently im using 1500 according to ati tray tools... which is impossible and it was call of duty was running as smooth as ever... weird??

it uses system ram also.

so i could theoretically run the game look the the ati tray tools number the quickly alt tab into the processes section of task manager then take the total memory and - the system memory to get my vram? or is it not this simple. Also is there a 2gb 6870 on the market which i could get to resolve the problem.
 
Weird how mine says 2gb when it can only use 1 gb theoreticcally :S

Dont see how im running out when theres like 5gb available to it or is this info wrong?

After reading your comments, so this is why basically the new graphics cards I see have 3 gig of ram to make up for these issues with people that want to use crossfire and 3 monitors?

So in a way you could just think of the ram on your graphics cards in that situation as overriding your system memory coz you said the vram on the graphics cards is faster then the DDR3 ram on our PC's so therfore is there any point buying loads of ram anymore on PC if we already got loads on graphics card?

Like maybe in future if we got 3 graphics cards with 3gig of ram on each then instead of buying 8gig or 16gig memory in our PC's we could just buy 4gig of memory? Or am I missing something?

No, like it got said earlier you would only get the 3gb vram not 3x3gb because it only uses one cards worth :(

Tempted to buy a 6990 next year when the prices drop as that has 4 gb which would sort me out for a longgg time, i guess the 4gb actually works out as 4 gb or does it only use 2 gb because of the whole crossfire thing or is internal crossfire different?
 
vsync off
triple buffereing disabled
4x AA via game settings
all settings in game maxed

also same thing is happening with company of heroes, i get like 20-40 fps yet gpus arent maxed.

I think your probably right about the old game engine idea. As i didnt think 3 x 1680x1050 was too huge really compared to some people running 3 2560x1600 monitors

Although i think i do run into i vram bottleneck when playing dirt2 with 8xmsaa as it drops to like 4 fps if that and i cant even navigate that goddam menu interface. Although a 2xmsaa is perfectly playable.

Also if i do run into a bottleneck from my vram in newer titles what do you suggest? I saw you wrote lower draw distances and turn down textures, and im guessing from my own experience turn down aa. Anything else?

Same thing is still happening with cat 11.3. Tried crysis warhead earlier all settings at mainstream with no aa @ 5040x1050, at only like 40-50fps and my gpus were only at like 75-85% usage and this is a game that definately supports crossfire well. vsync triple buffering etc are definately off :(

I think it is still because of CPU bottleneck.

It's not so much that a i7 930 at 4.4GHz being not fast enough, but more to do with Crysis/Crysis Warhead are written to run as only dual-threaded (if I'm not mistaken), so the 3rd and 4th cores on a Quad-core CPU doesn't help in the game.

No its not maxing any cores, ohwell :/
