Kevin Firth 114 Posted March 14, 2015 Report Share Posted March 14, 2015 Seems changing this value in 2.5 from 0 to 1 (its in the [sIM] section of the cfg) is gaining people between 5-10 fps with no downside... Going to have to give it a go.. K 1 Link to post Share on other sites
mutley 4,498 Posted March 15, 2015 Report Share Posted March 15, 2015 Thanks for sharing KF! Does it work? Link to post Share on other sites
Kevin Firth 114 Posted March 15, 2015 Author Report Share Posted March 15, 2015 Didn't seem to for me I'm afraid - the LM quick and dirty explanation is that it optimises complex models at run time, but I'm wondering whether it has a more profound effect depending on your GPD manufacturer...Im on a Radeon 7950 but clearly many other people are reporting approx. 15% fps increase with no reported downsides...possibly they are on NVidia GPU's? It's a no risk tweak though, you can always set it back easily enough, so worth a try on any rig - if it works for you then great, if not, no loss K Link to post Share on other sites
MyPC8MyBrain 273 Posted March 15, 2015 Report Share Posted March 15, 2015 works for me, the tweak appears to be DX11 dependent, so it may not be compatible with all GPU's Link to post Share on other sites
Christopher Low 63 Posted March 16, 2015 Report Share Posted March 16, 2015 Haven't you just purchased an Nvidia card, Kevin? I saw an AMD card owner report over at AVSIM that they couldn't see a difference, but plenty of Nvidia owners have been skipping around the schoolyard with glee! Link to post Share on other sites
Kevin Firth 114 Posted March 16, 2015 Author Report Share Posted March 16, 2015 I did Chris, then I cancelled it, as SWMBO expressed dissatisfaction to the n'th degree causing me to fear for my wellbeing Link to post Share on other sites
MyPC8MyBrain 273 Posted March 16, 2015 Report Share Posted March 16, 2015 chicken! read - http://www.prepar3d.com/forum-5/topic/optimize_parts-what-does-it-do/#post-102880 you may locked your profile on lower setting from your previous GPU if you delete your profile folder; it will be rebuild and DX11 option would be enabled for you Link to post Share on other sites
Kevin Firth 114 Posted March 16, 2015 Author Report Share Posted March 16, 2015 can u explain further pls Chris? my install was complete from scratch a few months ago so there should be no previous 'profile' in existence? K Link to post Share on other sites
MyPC8MyBrain 273 Posted March 16, 2015 Report Share Posted March 16, 2015 sure matewhen you first run P3D after a fresh new installa little wizard runs that attempts to give your PC optimal settings based on your existing hardwareonce this profile is set; some aspects of it remain constant; like the use of DX10 or 11 is set at this pointi haven’t found out yet how to reverse this selection; as these aren’t clickable switches inside the config tool to have your machine profile reevaluated you will need to delete your current user profileand run P3D again; and hope you get DX11 compatible profile with your new hardware you can read about down-level hardware herehttp://www.prepar3d.com/SDKv2/LearningCenter/getting_help/getting_help.html(go toTroubleshooting Video Card Support section) 1 Link to post Share on other sites
britfrog 180 Posted March 17, 2015 Report Share Posted March 17, 2015 apparently this mod also works for FSX so will try it later Link to post Share on other sites
MyPC8MyBrain 273 Posted March 17, 2015 Report Share Posted March 17, 2015 well...it doesnt! Link to post Share on other sites
britfrog 180 Posted March 17, 2015 Report Share Posted March 17, 2015 Chris I think I have to disagree with you, without a proper frame counter, just the stock fsx one i think I am getting on average about 3-4fps better (say 10%) using the aerosoft airbus, it certainly isnt making things worse at any rate Link to post Share on other sites
wain 879 Posted March 17, 2015 Report Share Posted March 17, 2015 if this is a fix for DX 11 then surely it wont work with FSX..... Wayne Link to post Share on other sites
MyPC8MyBrain 273 Posted March 17, 2015 Report Share Posted March 17, 2015 you don’t have to disagree Nigel; you elect to (I'm kidding of curse) for me it actually made things less happy in FSX, using stock counter and my normal settings i don’t see the point in messing the counters averages to see a finer fluxuation; which is measured by a different formula then I’m used to sample, if there are gains to made; it should reflect through the normal FSX counter formula as it does on P3D with this tweak Link to post Share on other sites
Christopher Low 63 Posted March 18, 2015 Report Share Posted March 18, 2015 Does this tweak work in both Limited and Unlimited framerate modes? Link to post Share on other sites
phil white 274 Posted March 26, 2015 Report Share Posted March 26, 2015 I have just tried this. Mine was set as zero but I changed it to 2.5 and got about 10 FPS increase. Link to post Share on other sites
