PC Specifications and Add-on Development
Introduction
I know some of you like to know what hardware I develop my routes on, perhaps because you're not sure what components should be used in a computer system suited to openBVE or BVE Trainsim, or partly out of curiosity, or partly so you can get an idea about what kind of system might be needed to see a similar level of performance to that which I experience. Apart from my first ever PC, I've assembled all my computer systems myself, as usually a much better computer that's suited to my needs can be built this way. Occasionally I'm asked what software I use for add-on development as well, or what techniques I use. On this page you can find out what hardware I'm developing my routes on, along with what I've developed on in the past, as well as see what kinds of add-ons I've been able to produce thanks to each new generation of hardware.

Development PC -- Where the Magic Happens
|
My current development system is built to be fast enough to cope with anything I'm likely to be doing for quite some time. Faster hardware consumes more power, so power saving technologies are enabled as well, and the CPU isn't being overclocked so it'll have a longer life. The following openBVE add-ons are being developed on it:
- Birmingham Cross-City South v1.4
- Watford Junction to Rugby

openBVE works extremely well with this graphics card and these drivers, however BVE 4 seems incompatible with NVIDIA's Windows 7 drivers, therefore I no longer use BVE 4. |

Faster hard disks can help when loading high numbers of 3D objects, as with Watford Junction to Rugby.
The SSD is used to store the operating system only. In order to minimise the amount of writes to the SSD, and hence maximise the life expectency of the drive's MLC NAND flash cells, the ProgramData and Users directories are stored on the WD VelociRaptor, with NTFS directory junctions pointing to these folders on the SSD, making it appear to applications as though these folders also reside on the SSD. This gives great real-world performance, mainly due to lower access times, and leaves plenty of free space on the SSD, which is important for performance with such a storage device. Also, both the SSD and 2.5 inch WD VelociRaptor drives only consume about the same amount of power as a single conventional 7200rpm 3.5 inch hard drive, while performing much better. |

After having three cheap PSUs fail in recent years, I thought it was about time I fitted something decent in my main system. This PSU is capable of delivering more power than is needed, so fewer amps are actually used, and the PSU will last longer as it's not being over-stressed. |

Previous PC Specifications (2009 - Present)

Currently a spare PC, this machine will be used occasionally for testing the performance of routes on slower hardware. This system was built on a tight budget at the start of 2009, re-using some old hardware. It was used during the development of the following openBVE add-ons:
- Birmingham Cross-City South v1.4
- Watford Junction to Rugby

This card (together with the Athlon 64 X2 4200+ CPU above), is a little too slow to handle full anti-aliasing with animated objects in openBVE -- framerates are acceptable, but there is some stuttering. This card also exhibits some transparent texture edge colouration issues in BVE 4. |

Previous Computer Specifications (Late 80s - 1998)
|
Prior to starting out with BVE and the Pentium II system, my previous computer comprised an Intel Pentium 100MHz (P54C) CPU, 16MB RAM, Diamond Stealth 64 DRAM PCI and Orchid Righteous3D (3dfx Voodoo I) graphics cards; the addition of the latter seemed amazing at the time, being used to accelerate 3D graphics in the flight simulator, EF2000. Before that, my first PC (and last ever ready-built, brand name system) was a Packard Bell Executive Multimedia PC running Windows for Workgroups 3.11 and MS-DOS 6.22, with an Intel 486 SX2 50Mhz CPU, 4MB RAM, 2x Matsushita-Kotobuki/Panasonic CD-ROM drive, 341MB Seagate hard disk, and on-board Cirrus Logic graphics solution. Both systems still work, although the P100 motherboard's floppy disk controller is dead. Before the PCs, came the Commodore Amiga A600 running Workbench 2.0 which introduced me to GUIs, computer based graphics design and animation, sound sampling and tracker music. My first computer was the Sinclair ZX Spectrum +2A, which introduced me to BASIC and simple train/flight sims.
