Slow Frame Rates - 8800 GTS

Just installed an 8800 GTS (BFG Tech card) in a PC with Athalon 64x2 and 2
GB RAM. This was to replace the onboard NVidia 6150 LE chipset for better
performance with MS Flight Sim X. Frame rates have improved (about 15), but
not to the point others are reporting (70+) with similar graphics detail.

What other factors on the card or PC could be holding back performance of
this card?

Settings. I'm sure that the others have them set down compared to yours.
What are they running rez wise as to you ?
Are they over clocking there's and your not ?

To many factors. Ask them. I'm sure they will share the tricks with you.

One more question, after reading the links, about power supply.

If the unit has a 400W supply, can one assume the amperage at 12 volts is
400W/12 = 33 amps? This card needs 26A at 12 volts.

First let me assure you NO one and I do mean NO one is reporting 70 + frames
flying FSX even with All Sliders to the Left and using a better board than
yours... the 8800 GTX or the Ultra and with... the fastest, meanest ugliest
processor known to man. It will not happen this year even. CPU power isn't
there yet to drive FSX to 70 FPS.

Have you installed the Service Pack 1 for FSX? It is here...
http://dev.fsinsider.com/Pages/default.aspx

With it installed you might be able to get 20 frames depending on your
processor. A good test is the Cessna 172, at 500 feet off the ground. New
York. Take her downtown.

Also best to ask this question here...
alt.games.microsoft.flight-sim

Lots of smart folks there. Also the web page I referenced above for the
service pack... well it has a few tips, etc.

Have a good one and don't worry about 70+ frames. It's not happening in
this world.

No. It should say on the power supply. I'd get a 750 watt my self.

Other stuff in your computer is using the 12 volt line also. I'd say the
computer power supply is ok for the original computer. Just. Manufactures
usually don't build in much of a safety margin. Then you add a card that
wants 26 amps. Yeah a 750 watter will work. BFG has a nice 800 watt unit.

BFG also has a 650 watt unit...
http://www.bfgtech.com/bfgr650wpsu.aspx

scrolling down and downloading the PDF spec sheet shows two 12 volt rails at
20 amps each.

There are other power supplies too...

64 X2 what? There is a wide speed range between the slowest and
fastest. ( Slowest is a bit over 2 Gig with the 6000 core running at 3
Gig)
The frame rate is highly dependent on the core clock, FSB, and memory
with the core being the main factor in FSX. SP-1in FSX has helped
with multi core machines, but some configurations reportedly do not
like SP-1. I've had no problems. Also AMD has a dual core driver that
makes a difference and another if you are running XP Pro. Both of
these will *probably* make a noticeable difference.

GB RAM. This was to replace the onboard NVidia 6150 LE chipset for better
performance with MS Flight Sim X. Frame rates have improved (about 15),

To 15 or by about 15?

but not to the point others are reporting (70+) with similar graphics
detail.

Not many are running 70+ and those are not running with all sliders at
max. Plus they have done a lot of tuning.

Backing off on the AI traffic, ground traffic and some of the other
settings will, or should make a noticeable difference. I've forgotten
which of the graphics settings for the 8800GTS will speed things up
but there is at least one that is reported to make a noticeable
difference.

Settings. I'm sure that the others have them set down compared to yours.

Most likely true.

I'm running an FX62 and a 64X2 6000 with frame rates on the order of
20. I can get 30 at altitude, but I have all sliders at max.
I would get a much higher frame rate by backing off on some of the
settings.

One thing I have noted it the X2 6000 runs much cooler than the FX62
running FSX and the same background processes.
Another is my AMI X1950XT 256 Meg is slightly faster than the 8800 GTS
640 on the FX62 while the 8800GTS *appears* to be slightly faster on
the X2 6000.

What are they running rez wise as to you ?

Both of mine are running 1680 X 1050 on 226BW monitors.

Are they over clocking there's and your not ?

I'm not, although both systems offer dynamic overclocking.


To many factors. Ask them. I'm sure they will share the tricks with you.

However if you read some of Tom's evaluations you will find that in
some cases the CPU can slow the GTX to the speed of the GTS or even a
tad slower and I'm sure that dated prior to post on the above link.

There's a lot of misinformation in that thread. Read the evaluations
done by Tomshardware.

http://www.tomshardware.com/2006/11/...e_fastest_cpu/
is a start and it does predate the thread above.

There are about 4 or 5 on there with the new top end Intels making
that claim which is probably why he's expecting far more than what
he'd getting. I don't know of any one making much over 30 or 40 with
the Athlons and I have both the FX72 and X2 6000 running FSX. OTOH
I've not tried to tune for maximum frames. I went for as much realism
as I could get and still maintain acceptable frame rates. Those frame
rates are far less than a gamer would settle for but they work fine
with FSX.

FSX is mainly CPU & memory dependent.
