The "default" renderer does not use shaders at low settings.įor really marginal systems, before switching to older FlightGear versions, it's recommended for people to try running latest FG with lower settings, older renderers like shaderless, older terrain (e.g.
#Flightgear tips professional
In DiY (home cockpit) or professional simulator settings FlightGear is run in complex configurations.įlightGear keeps renderers from older eras, has lots of settings configurability, has multiple weather and physics engines with differing requirements, and is mostly backwards compatible with older versions of aircraft. weak GPU or laptop) hardware in research and education settings.
#Flightgear tips software
Medium, Low, and Minimal settings requirements Ī large range of hardware is supported than normally expected - as FlightGear is an opensource scientific and engineering software historically from the Linux community, and is run on non-gaming (e.g. With high object count FlightGear is more demanding of CPU. More complex craft can tax both CPU and GPU. Better GPUs for higher resolution, or higher AA/TRAA.
#Flightgear tips plus
Object load distances also use more RAM/VRAM: FlightGear can also create somewhat realistic tree and bush densities, as well as draw every single building in open street maps, plus auto-generated buildings, for the load distance you specify.ģ2 GB of RAM for large draw distances for terrain and/or objects. Once realistic draw distances option is selected, FlightGear will remove the limiting fog as weather visibility and max load distances allow - including ignoring METAR in "live" weather mode once it reaches upper limit of 9999m. On clear days, and from high altitude looking down, distances can be huge (many 100s of km+). GPU: GTX 1060 or AMD equivalent for super-sampling Transparency AAįlightGear can do realistic draw distances.CPU: 4 core i5 4xxx or AMD Ryzen equivalent.Can turn up GPU heavy settings like AA/TRAA. This build will be strongly CPU bound.You can get away with a recent high frequency 2 core CPU. CPU sandy-bridge i5 2500k or equivalent.Visuals target: somewhat high-ish settings examples Minimum LoD:range rough influences range at which objects including trees load, turn this down if RAM is low or CPU bound in areas with lots of objects. Turn off world-wide AI traffic if CPU is slower, turn off building & road layers, or use random buildings only. Advanced Weather), terrain driven weather, cloud shadows, cloud density & distance: max, Anti-aliasing: MSAA 4x or 8x, transparency AA (adaptive AA on AMD) set to MSAA, scenery load distances (LoD ranges setting): default.

#Flightgear tips 1080p
Performance target: 1080p (1920 x 1080) resolution, 30+ FPS with Cessna C172P. As the FlightGear project is volunteer based, the screenshots gallery is what was available in the wiki - roughly high-settings and roughly representative of 2020.3 at somewhat high-ish settings.įlightGear's GPU programming can support high-ish settings on a GTX 1050 Ti at 30+ FPS at 1080p (fair amount more than 30 FPS, depends). It's not trivial to find exact specifications, even for commercial applications with lots of test systems. The familiar max settings galleries as provided by commercial products like games are meaningless for this - below the max hardware limit. A separate gallery is needed for each group of target settings. Screenshot galleries: What people want is to see what a sim looks like on hardware people actually have, and at a desired target performance and resolution.

In DiY (home cockpit) or professional simulator settings FlightGear is run in complex configurations - see input and interfacing on the main article.

System requirements are a complicated topic.įlightGear supports a larger range of hardware than normally expected - as FlightGear is an opensource scientific and engineering software historically from the Linux community, and is run on non-gaming (e.g.
