PC Performance Guide

This guide is a research tool developed to provide flight sim enthusiasts and DIY pc builders a quick and
easy resource to determine the best performance components for your flight sim rig.

Jetline recommends upgrading your system in the
following priority to maximize Flight Simulator Performance:

1. Processor (CPU)
2. System Memory (RAM)
3. Graphics Card (GPU)
4. Hard Disk Drive


Processor (CPU) Performance

Choosing your Processor
The processor is the most important component you will
choose in a high performance flight sim pc. Make this component
priority one when planning your system specs. Currently
Jetline Systems strongly recommends Intel processors as they
have consistently outperformed AMD in Flight Simulator.

FSX Performance
Up to 75% of your frame rate is produced from the CPU.
Quad core processors will improve frame rates with
increased auto gen scenery, traffic, and weather generation.

Intel Core i7 technology has proven to be the biggest
impact upgrade for FSX performance. The latest Core i7
Haswell CPU's have proven to be the best performing
CPU's for FSX. The 4770k and 4670k processors provide top
performance while running demanding aircraft, traffic and
scenery add-on programs.

AMD FX-9590 (4.7GHz) Eight Core

AMD FX-8350 (4.2GHz) Eight Core

AMD FX-6300 (4.1GHz) Hex Core


Memory (RAM) Performance

Choosing Your Memory
Consider both memory clock speed and CAS latency timings
when selecting a performance memory configuration.
Jetline uses only low latency memory.

FSX Performance
Memory clock speed is an important component to any high end
rig. The secret to high performance memory is the CAS latency
(CL #). This information is not commonly published in
off-the-shelf computers. CAS latency is a timing reference to
how many processing cycles are required to read 1 pass of
memory data. The lower the CL number the faster the memory.

Good: 8GB DDR3 SDRAM @ 1600MHz (CL10)
Better: 8GB DDR3 SDRAM @ 1866MHz (CL9)
Best: 8 GB DDR3 SDRAM @ 1866MHz (CL8)

FSX SP2 Memory Performance (Clock Speed)

DDR3 SDRAM (2133 MHz)

DDR3 SDRAM (1866 MHz)

DDR3 SDRAM (1333 MHz)

FSX SP2 Memory Performance (CAS Latency)





Graphics (GPU) Performance

FSX Performance
Only up to 25% of your total frame rate is generated from your
graphics engine. We recommend the Nvidia GTX 780 (3 GB)
graphics card for best performance now and keeping your rig
ready for future.

Multi-GPU Impact on FSX
Our testing has proved that SLI and Crossfire graphics will
only decrease the overall performance in Flight Sim.
The new 700 series cards have the ability to run 3 monitors
from a single card either individually or spanned (TH2GO effect)
The GTX 770 and 780 are strongly recommended for muli-display

The Nvidia GeForce GTX 690 and other dual GPU graphics cards
to be a significant performance decrease to FSX. This is due to
their integrated dual GPU design. Jetline is not offering these
models due to low FSX test results.

Hard Disk (HDD/SSD) Performance

Choosing a Hard Drive Configuration
Jetline recommends installing dual hard drives in your system.
The primary hard drive is a traditional rotational drive installed
with an additional 64GB SSD to work as a high performance cache
Once installed, Windows boots and runs up to 6 times faster than
a standard HDD giving your computer close to the speed of an SSD
with the capacity of a traditional drive at a great price.

Common Configuration Examples:
Primary Hard Drive: 1TB 7200RPM 64MB SATA 6GB/s
Secondary Hard Drive: 64GB SSD Accelerated Cache
Primary Hard Drive: 1TB 7200RPM 64MB SATA 6GB/s OS and FSX
Secondary Hard Drive: 1TB Storage and Backup Drive)

FSX Performance
In order to maximize FSX performance you will want to either
select an SSD accelerated setup or a single SSD.

RAID 0 Impact on FSX
Many gaming PC companies are offering RAID 0 performance
configurations. This is a good configuration for PC GAMES, but
not Flight Simulator Programs. Onboard RAID 0(pairing hdd's)
can significantly reduce FSX performance.
