First of all I am not writing this to rub anybody's nose in it. I know how things can be taken on these forums. I am writing this in the case that it may help someone who has had trouble with low framerates.

 

After purchasing the 777 I found that I had low framerates. I tried all the tweaks I could find on the net and none made much difference so I set too reformatting my drive, reading plenty of forums and reinstalling windows and FSX.

 

I have FSX on a second drive so I formatted the drive with 64 kilobytes allocation size as I read this was quicker to access.

 

I then downloaded FSXMARK2011 and set too benchmarking my basic screen. I tried different tweaks and found that none of them made any difference to the FPS. The only one that made a difference was bufferpools which dropped my FPS by about 7 fps. Overclocking my I5 3750K to 4.6 helped as expected. I have added HIGHMEMORY=1 and TEXTURE_MAX_LOAD=4096

 

This was when I found that I could use my onboard graphics to work with my Geforce card with the use of Virtua MVP. Now I know not all system have onboard graphics and out of the ones that have, not all can use Virtua MVP so if you don't have it then you need not read any further.

 

For those who have this increased my frame rates by 7-8fps. From what I can tell Virtua MVP used the onboard graphic chip to process any 2D images and the PCI-E card to process the 3D images. The only problem I found was that if I set up Nvidia inspector then I would end up with a blank screen. Without this I was left with jagged edges. I finally found a work around by using FSX's Anti-aliasing with no poor effect.

 

My specs are listed but I know have the VC of the 777 sitting on the runway at UK2000 EGKK, Fraps reading a steady 30fps on a screen 5213x1050 and REX textures.

 

My settings are;

 

Target frame rate: unlimited

Filtering: Trilinear

Anti-aliasing: ticked

Global texture resolution: Very high

Aircraft: Medium high

Detail radius: Large

Mesh complexity: 100

Mesh resolution: 1m

Texture resolution: 7cm

Water effects: Mix 2.x

Land detail texture: ticked

Scenery complexity: Extremely dense

Autogen density: Extremely dense

Special effects detail: High

Cloud draw distance: 70miles

Thermal visualization: Natural

Cloud coverage density: Max

Traffic is at: 20 20 Low 0 20 20.

 

Hope this helps someone

Virtua MVP? I googled it, it appears you have to pay ~$30 for it.. 

Doesn't it come free with some hardware components? The name rings a bell..

TEXTURE_MAX_LOAD=2048 for me ... and the correct entry for the HIGHMEMORY=1 is HIGHMEMFIX=1.

 

 Won't comment on the rest of the OP ...

VirtuMVP came with my comp... maybe your running at such low FPS because of the large resolution your running at. I know when I tried to run FSX on my flatscreen TV my Video Card nearly flipped out.
