I have recently upgraded my hardware to increase the performance of FSX with my addons.
2 weeks ago I changed my AMD Phenom II 1100t Black Edition 3.3MHz processor to an Intel i7 4770k processor and Over-clocked the processor from 3.5MHz to 4.4Mhz. The difference was amazing, but still if I use the PMDG 737 with UK2000 Gatwick Extreme, my frame rates drop to around 15FPS.
I used to have an NVidia GTX 480 Graphics Card, so I thought that may be throttling the performance, so today I purchased an NVidia GTX780 (MSI Over-clocked Edition) thinking that would solve the problem. But it hasn't really made any difference.
I have most of the settings on high, but not all maxed out, I have played with the settings and unless I start changing them down too much, the performance is not great using those 2 add-ons.
Now if I use the PMDG 737 anywhere else its fine, and if I use a standard FSX plane at Gatwick, its bearable (but not great).
I thought with the hardware I have recently purchased, I should get a smooth experience with both add-ons at relatively high settings.
My system stats are:
Asus Maximum VI Hero Motherboard
Intel i7 4770k (OC'd to 4.4Mhz)
Corsair H100i Water-cooler
8GB Corsair Vengeance 1600MHz DDR3 Ram
MSI NVidia GTX 780 Over-clocked Edition
4 x Corsair SP120 Static Pressure 120mm fans on Push/Pull on radiator
3 x Corsair AF120 Case fans
Corsair Carbide 540 Air Flow Cube Case
