Author FS9--dual core and SLI?
grannygamer

2006-08-28, 7:38 pm

My husband is thinking about getting a computer that has a dual core CPU
(4800+) and SLI video (256--Nvidia 7800). While he's not a heavy gamer, he
does load up FS9 on occasion. Does FS9 run well with this setup or are
there known issues?

I don't believe FS9 was written to take advantage of dual core CPU's and I
don't believe that FSX will either (when it comes out).

Having said that, you do get a noticeable improvement in game play when
using a dual-core over a single core. This is because you can have all your
background tasks/programs set to run on one CPU and the flight-sim on it's
own on the other.

As far as I know, there are no issues either.

FS9 made little use of dual-core but FSX is much improved:

Thanks; was primarily concerned about possible issues, especially with SLI,
more than with seeing a performance burst. I know he'd hate to spend the
money and then have his one and only game run badly. Appreciate the
responses.

FS9 doesn't use SLI.

No, it can't.

Ummm, the way SLI is implemented nowadays, the software doesn't do anything
anyway. It's all handled by the hardware, so FS9 will still use SLI because
it's the hardware performing whatever SLI is happening anyway.

Maybe if FS9 was running on an old 3DFX SLI implementation it would be a
different story, since that was handled by the software, but nowadays it's
not.

Maybe you were talking about multiple cores rather than SLI, in which case
we've already covered that?

No it won't. I have FS9. I have SLI. FS9 does not use SLI.

I'm sorry, I don't understand what you're talking about.
No software uses SLI. It's a hardware implementation.

btw I have FS9 too and I also have an SLI set-up (two 7900's) and the game
runs just fine, which means the hardware is implementing SLI perfectly. If
it wasn't, I would only see half a screen.

Compatability with an SLI setup is a big difference to actually utilising
SLI. When I first put my rig together 18 months ago, FS9 and many other
games wouldn't even run unless SLI was disabled in the driver. Later drivers
have improved that so that now you can leave it enabled and those games that
can't utilise SLI will run, but in single card mode.

The reason you don't see half a screen is because your primary graphics card
is running the whole show.

Enable "Show load balancing" in your drivers. You'll see no balance display
because you're running only one card. Do it in the FSX demo and you will,
because FSX can use SLI.

Disable SLI.in your drivers and run off one card. You'll notice no
difference in performance with FS9...

Sounds like Toosmoky is making sense to me!

Now, TooSmoky, what do you know about Oleg's intentions for the forthcoming
"Battle of Britain"?

Yes. The software doesn't really care. It outputs what it wants to display,
but the hardware just splits the tasks amongst the two video cards as
needed.
