How taxing is FSX on GPUs?

[LoneWolf121188]

Even though I've got my 6800s cranked up to 410MHz/1100MHz, it seems as though its not really using the GPUs that much. Why? Because according to the nVidia control panel, my temps never get above 70C, but in a test of 3DM06 I just ran, I was pushing 97C! No visible artifacting at those temps, but its quite obvious that 3DM06 is using my GPUs more than FSX is. Is that just how the game is designed or am I missing something?

If the performance is going fine, it might just be that it doesn't require the cards to work enough to get to those temps. I've also noticed that different games/apps push the GPU differently. I get my highest temps running FEAR. More than 3DMark, ATITool, anything. Might be the case for you.

Ditto, FEAR is also the app. in my software collection that gets my card the hottest. I usually hit 60 when playing it, 55-57 when playing Oblivion or GRAW, and measly 45 when playing D3. When playing my combat flight sim it will also rarely break 45°.

I say we all gather round lonewolfs gfx card s during 3dmark and cook something . ya, some programs use gpus differently. same way if an O/C fails a run at prime doesnt mean its gonna give out on you during normal use. Theres just a good chance.

Thats the thing though, its not. Its stuttering along at about 25fps. Enabling SLI doesn't help much either. I'm really surprised it doesn't have dual core support, I think that would help a ton. Any ideas on how to force dual core support or something like that? I've got it running on two monitors, any way I can set it up for one core per monitor or something?

If it's running dual monitor, it must be going at a high resolution. It may just be too much for dual 6800GT's

Its actually not 2560x1024, its two seperate screens of 1280x1024, one fullscreened on each monitor. FSX doesn't actually have true multi-monitor support (one view that strectches across multiple monitors), you have to create a new view window, move it to the correct monitor, then change the viewpoint, angle, and zoom to get it to line up with the one(s) you already have open. Its quite annoying, but it works. So each card is powering only one view.

I have battled with FSX for 3 weeks,I had AMD 3800 X2 2X 6800 VGA,2 gigs of memory,and I could only run FSX on miminums with no AI traffic no nothing,graphics as low as you can get them,and I still only got 15 to 20 FPS.
SO i went and got two 7900s and an Opty 170 and still no difference,so I sent the 2 7900s back for an EVGA 8800 GTX and still low frame rates,there are many hacks and tweaks out there,you can hack the cfg file and all that but I won't do that,I got FSX because it was supposed to be better than FS9,well it sin't if you have to hack the crap out of it and fly in the sky with no traffic.
In the flight sim community some love it even though they have to hack it to get it to work reasonably on there systems.
This is a sore spot for me cause I fell into the trap and went and spent big money because of a sim.
How many unsuspecting people will see FSX on a shelf in Bestbuy and see the requirements of a 32 meg video card and a 1 gig CPU anf take it home to be greatly disappointed?
On the good side,I have a DX10 graphics card so I am ready for the future
Sorry for the rant,I just can't help myself

A little info on the ACES team who developed this sim..

FS X seems to me like it is very intense on your ram with all the textures and whatnot. Since I only have 768mb I pretty much can turn up anti aliasing and the water effects, however I need to run the textures and details a bit lower, and even then I still get only about 10fps.

If both 1280x1024 screens are in 3D, then the video card is working with 2560x1024 at the same time. It has to draw each screen.
