Recently I had an opportunity to re-install FlightGear (stable ver. 2020.3.19) on my 2013 Mac Pro and was pleasantly surprised - with no crashes, decent FPS for the most part, and various other improvements that were incorporated over the years. I had dabbled briefly in FlightGear a couple of times before (around 2013, and again around 2020) - but eventually removed the flight simulator from my hard drive on both of those occasions. Since my particular setup(s) are with dual AMD video cards, I thought I would post some (illustrative) tips below, as well as representative pics of the sim when at best, or very good, settings. I will this time around keep FlightGear on my hard drive - makes for a good, free flight simulator. For command line entries and tips that should be plugged into the "Additional Settings" option of FlightGear, see the info. immediately below. Make sure to remove the info. included in brackets if copying the commands into the relevant settings section. ----- --prop:/sim/gui/current-style=0 (better GUI style for AMD cards) --prop:input/mice/mouse/mode/button[2]/binding/value=2 (gets rid of horrible mouse-as-yoke feature that sometimes automatically turns on) --prop:/sim/rendering/photoscenery/enabled=true (gives more photo-realistic scenery whenever possible; to be fully implemented in later FG versions) --prop:/sim/rendering/hdr/envmap/update-continuously=false (disables continuous siphoning and updating of terrains, to enable seconds command below) --prop:/sim/rendering/hdr/envmap/update-rate=5 (terrain refresh rate set in seconds; good values are 5 or 10, for minimal stuttering) --prop:/sim/rendering/max-paged-lod=1300 (stock max paged LOD no. is "200"; recommended is not to exceed about "1900" on AMD) --prop:/sim/rendering/plod-minimum-expiry-time-secs=60 (stock min expiry time is "180" secs.) --prop:/sim/rendering/multithreading-mode=DrawThreadPerContext (should improve multithreading capacity, at least slightly, and add a few extra FPS) --prop:/sim/rendering/database-pager/threads=12 (stock thread rendering no. is "4," with more threads improving ave. FPS; set as per your CPU threads no.) --prop:/sim/rendering/vsync-enable=false (force disables vsync to improve FPS) --prop:/sim/rendering/multi-sample-buffers=true (this is anti-aliasing; set to false to disable and remove entry immediately below it) --prop:/sim/rendering/multi-samples=2 (anti-aliasing value; lowest is 2, also good is 4; avoid 3) --compositor=Compositor/HDR/hdr (modern rendering pipeline for better graphics details and shaders; rarely breaks scenery; still mostly experimental on AMD vid. cards) --units-meters --disable-splash-screen --disable-horizon-effect --enable-distance-attenuation --enable-specular-highlight --enable-clouds3d --fog-nicest ("nicest" improves look of fog with more subtleties while "fastest" makes fog appear and disappear more quickly; no real impact on AMD FPS) --shading-flat ("smooth" apparently improves look or depth of shaders; preference is for "flat" since I have not noticed difference in quality on AMD) --texture-filtering=2 (this is anisotropic value; lowest is 1; also good is 4 or 2; avoid 3) --bpp=32 (can also use 24 but have not noticed an FPS improvement with 24; would say 32 is better for FPS overall) --terrain-engine=pagedLOD --lod-levels=3 2 5 3 1 (also good is 4 3 6 4 2 for best visual quality on AMD but still mostly FPS-friendly; recommended is 3 2 5 3 1 for balance between visual quality and solid FPS) --lod-res=2 (default is 1; also good is 3; avoid any other values besides 2) --lod-texturing=raster (better than "bluemarble" as far as I have been able to test, with smoother loading of textures) --lod-range-mult=3 (default is 2; also good is 1; avoid all other values besides 3) --enable-texture-cache ----- On a broader note, it's important to tweak the rendering, shaders, and LOD range settings in FlightGear - to get the best experience on your AMD video rigs (be it a dual or single AMD setup). The frequencies, by the way, on my dual FireProD700s have been OC-ed, via MSI Afterburner, from a clock/memory of 850/1370 to 1024/1380 MHz. Be sensible with the rendering options - particularly with the maximum number of scenery and aircraft tiles - anything above a value of 1900 or so is both useless and an FPS hit. (The scenery/aircraft tiles no. may also be set via the relevant command line entry indicated above in this post.) Take note as well of cloud density and visibility values. Anything beyond a visibility of 35 km or so is questionable since it does not widen further the cloud carpet but is, once again, an FPS hit. Pic 1 - Sensible/Best Rendering Choices for AMD Video (in FlightGear) Next we look at the shader options that also require careful thinking and tweaking. Take note that "landmass," "urban," also "water" - give different visuals if they are set to the maximum level (of five). I personally prefer how the landscape/terrains look with those three settings at a value of four - with crisper graphics - but tweak according to taste. Also worth noting is that I always run the LOD value on my rig(s) at "-1," via the excellent little program "ATISetLod" that is available under the top post of this thread. Pic 2 - Sensible/Best Shader Options for AMD Video (for crisp and fairly realistic graphics) Also important is to tweak the LOD range settings to get a good balance between visual quality and decent FPS, with no stuttering or crashes. Focus in particular on the maximum distances for the detailed, rough and bare scenery ranges - I decided eventually on cutoffs of 3, 17.5 and nearly 45 km. Other cutoffs worth considering are 2.5, 15, and 40 (or so) km, as well as 3.5, 20, and 50 km. Anything beyond the latter values will, again, most likely not make much of a difference with the visuals but will contribute a noticeable FPS hit. Take note also of the "high detail" and "AI/MP interior" values. I'm getting good results with values of 250 - 260 pixels for those options; also good are values of 300 (or so) pixels. Those two values may be tweaked to taste, for the most part - but, again, be sensible since they may impact on FPS. Pic 3 - Sensible/Best LOD Range Values for AMD Video Last, let's not forget to tweak our custom FlightGear profile (in our AMD settings panel) as best we can, to minimize stuttering, pausing, or crashes. Take note in particular how the shader cache is set to "On," not to "AMD Optimized," and how, even though I have enabled CrossFire mode, frame pacing is set to "Off" (which eradicates stutters on my rig in FlightGear - had tried with frame pacing "On" and was not pleased with the results). If you have only a single AMD video card, experiment with leaving the CrossFire option on (set to "AFR compatible"), or turning it off entirely. (NOTE: I have not noticed any FPS downgrade with anti-aliasing set to 4EQ and edge-detect, anisotropic value at 8, and tessellation at 16. Tweak to taste obviously.) Pic 4 - Good AMD Settings for a Custom FlightGear Profile Recommended also, if having any instability with FlightGear on AMD video, is to stick with the "Pro" variant DLLs (drivers) for AMD, instead of the consumer/Adrenalin ones. I particularly like the ver. 19.x.x Pro series of drivers, as well as the venerable ver. 17.x.x ones (the latter of which I have installed on the 2013 Mac Pro). To find links to the Pro 19.Q3 DLLs (the last version of the Pro DLLs to support CrossFire, by the way), see this page. Below follow several representative pics with the settings illustrated above applied - FlightGear provides a nice selection of aircraft with usually very good monoplane FMs, especially for tricycle-gear (small) civilian aircraft such as Cessnas, also for airliners like the (classic) Boeing 707. For multi-wing contraptions on the other hand and more realistic/historical FMs for biplanes, triplanes, and the odd multiplane, the gold standard(s) remain heavily-modded First Eagles 2 and RoF, as well as recent iterations (UE edition onwards) of the excellent WoFF series. Happy flying, Von S

Apr. 17, 2023 Update - Please find, available at the link below, my previously released mods. for RoF United Ed. - this time as a convenient, consolidated package that has been updated with the latest tweaks. Do read the included "Read Me" files, where available, for more info., particularly the "READ_ME_ROF_General_Info" file that is located in the root folder of the package when unzipped. This package is provided "as is," with no active support beyond the included explanatory files. The "Consolidated Mods. New" Package contains the latest AI mod. (ver. 1.4) for RoF United, as well as mods. previously offered separately, such as the "M-S Type H Campaigning Tweak," the "PWCG modulations" files, etc. Apr. 29, 2023 Update - Included below the link to the "Consolidated Mods. New" package is Ver. 3 of the PWCG "modulations" files (to be installed manually in the PWCG ver. 16.3.1; see directions included in the larger, consolidated package). Ver. 3 of the "modulations" files increases wind and turbulence settings, as well as provides greater chance of encountering more capable AI when flying PWCG campaigns, especially if used in conjunction with my newer AI mods. for RoF (such as ver. 1.36 or 1.4, included in the big consolidated package). Important Note: if using the Ver. 3 PWCG "modulations" files, instead of the Ver. 2 ones included in the big consolidated package for RoF -- make sure to change settings, if you choose to change any, from within the modulations, i.e., the RofCampaignSpecific, files themselves -- otherwise, tampering with relevant settings from within the PWCG advanced menu options will automatically delete extra entries for the AI that I've included in the Ver. 3 modulations. This note does not apply to the Ver. 2 modulations since those don't contain any extra AI settings. Feb. 6, 2024 Update - RoF AI mods. vers. 1.36 and 1.4 have been upgraded to vers. 1.37 and 1.41, respectively. The new versions have tweaked the AI's ability to follow commands more quickly and/or properly. Ver. 1.41 also contains further tweaks to safe alts. for the AI, to minimize unnecessary crashes and very low-level dogfighting. The entire consolidated package has been renamed from "Consolidated Mods New" to "Consolidated Mods New V.2" (i.e., Version 2).

View File SF2 Cold War Prop and Flogger FM Tweaks Hello SF2 Flyers, For the post-WW2 prop. high-performance aircraft, several tweaks have been applied to the data inis, ranging from lift values for wings and wing tips to the engine section, prop. rpms, flight control section, gears section, flaps, also empty weight, inertia values, ceilings, engine sounds, rudder reversal effect fix, aileron/elevator/rudder sensitivity and movement, etc., depending on the type tweaked. Tweaks are not as extensive as for my FE2 work - but I've tried to get them into the "90% realistic enough" category for SF2 since these high-performance types are difficult to precision peg to within a km or two of historical stats., in contrast to the slower-moving FE2 types. Also included with this package are my minor data ini tweaks for several Flogger types, such as the MiG-23 S, early M, ML, P, MLA, late variant "98," and export variants MF and MS. Many thanks to the original FM modders for the late prop. types, including Baffmeister, Wrench, Cocas, MontyCZ, Charles of A-Team, Coupi, Paolopanz, and others I may not have mentioned here. The data inis are for SF2 installs only, tested at hard FM settings (no guarantees that the AI can land them nicely, although they fly them just fine). The Me109 G5 and H0 are variants on the stock G10 package provided on CombatAce (to install simply copy the relevant aircraft folders, rename as per my included folders, and drop in the relevant files). P-47 Sprint upgrades are variants on the ETO P-47D Bubbletop model and PTO P-47D Razorback model. Also included with this package are three sounds for a Pratt-Whitney, Centaurus, and Me109 either Benz or Hisso powered (sound works good for both). Links to the relevant aircraft that correspond with these data ini tweaks are located in the included "Read Me" file with the package. Please go through the Read Me for more thorough info. regarding these FM tweaks. Version 1.2 of this package includes the P-47N and improves the data inis for the other Jug and Superbolt variants.
