I recently purchased Flight Sim X deluxe and its completely unplayable.
I have changed all the settings to the suggested ones for my graphics card from Nvidia.com and then even put them at the lowest possible settings but still its runs like a absolute DOG!
Even at 1024 x 768 resolution its runs terrible as well as lookign 1/3 as good as my Flight sim 2004. It says I am getting about 20 frames per second but this is rubbish as true 20 frames per second would be smooth as. Every time I run the sim I get frustrated within a minute and shut the damn thing down.
I have the following system
- Athlon Dual core 4200 CPU
- Geforce 7900 GTX 512 mb
- 2 gig DDR2 ram
- SATA hard drive 320 gig
- ASUS M2N SLI mianboard
Your system seems quite good to run FSX. Try the tweaks here: https://forum.flyawaysimulation.com/forum/topic/22217/unofficial-tweaks-for-fsx/ and make sure that you don't have memory intensive applications running when you run FSX.
