Despite 2 GRAPHIC CARDs, FPS PERFORMANCE in FSX is still BAD??

[damlays 0]

I am running “FSX Acceleration” in my system seen the details as below.

But I don’t know why, my “Average FPS” cannot be more than 10/sec or 15/sec (sometimes average is even decreasing below 10/sec)

Mainboard : ASUS P8Z68-V GEN3

CPU : Intel Core i5 2320 @ 3.00GHz (Sandy Bridge 32nm Technology)

Graphics : NVidia GeForce GTX 650 (1023MB)

NVidia GeForce GTX 560 (1023MB)

RAM : 8,00 GB Dual-Channel DDR3 @ 668MHz

Operating System : Microsoft Windows 7 Ultimate 64-bit

I’ve read many forums about Tweaking fsx.CFG in FSX. But I could not reach any successful solution for a long time. So I decided to write here. I appreciate any help coming from forum users.

I can summarize my points in 3 items as written below;

1) Generally what is wrong in my system or configuration? Why average FPS never cannot go upper than 10-15/sec?

2) What is the right way for using capacity of 2 graphic cards together with maximum performance (in 2 monitors)?

3) There is one weird problem also I need to ask;

Nearly in all forums about performance tweaking, I see they are writing “HIGHMEMFIX=1 is a MUST HAVE Tweak”

But when I put it to fsx.CFG, FPS is dramatically decreasing to 5/sec or even below.

I cannot understand why everybody gets very good results from this tweak, and I am getting this result???

After trying, changing and testing many different parameters, this configuration below is the maximum FPS I reached (only 10-15/sec) :

FSX is very much about cpu. So this may be your bottleneck.

But what is affinitymask=84? I know how affinitymask works but I dont know why youve set it to 84. Maybe try it without affinitymask.

[Farlis 155]

1) Generally what is wrong in my system or configuration? Why average FPS never cannot go upper than 10-15/sec?

Because, as Jan already pointed out, your CPU is too weak. One that can be overclocked would be better.

[srcooke 422]

As Jan has pointed out the affinity mask is totally incorrect, a guess or from someone else's config?

I would start by backing up your fsx.cfg, delete it, restart FSX with one monitor and allow the cfg to rebuild and set conservative settings. See how that works out.

There is a tweaking tool by Bojote that still shows good results, IF you feed it the correct information : Bojote's Tweaking Tool

Or if your prepared to read and follow NickN's guide : NickN

Another by Kosta

Follow only one path, each takes a different view.

Start basic and work up to what your system can handle, as Karsten noted FSX is CPU intensive, throwing two graphics cards at it without CPU power is not likely to deliver a result.

[Aerosoft Team [Inactive Account] 51558]

Graphics card in SLI configuration are normally slower then one card in FSX. Under P3D it does help a lot!

And please don't mess with the affinity mask, just let FSX handle it, 99.999% of cases that is best. Only when you got weird 6 core CPU's it starts to make sense.

[srcooke 422]

Oh Mathijs,

Please don't call my six core Intel weird, it'll get upset

Oh Mathijs,

Please don't call my six core Intel weird, it'll get upset

Please apologize on my behalf to you CPU and feed it some amusing calculations to make it happy.
