Same here

This ! It would be a very useful addition

after some more tests, If I lower graphics settings and set these paramaters in graphic.lua : ExportScript.Config.ExportInterval = 0.08 ExportScript.Config.ExportLowTickInterval = 0.8 It's a lot better but not perfect. But not with the M2000... I had to set an even higher exportinterval to have a constant framerate.

Ok, I'm not alone !

@Guppy, I use Ikarus with the F15 and the M2000. But I will try with other module to check performance @McMicha, Yep. Game mode is disabled. It's worst with it enabled !

Hello McMicha, I've just installed the newest driver (419.35) on the oldest sim (the one with the 1080Ti), everything's still running well. So that's not a driver relative issue. I'm turning mad :wacko:

The older PC is running a 1080Ti with nvidia drivers 399.07 The new one, a 2080Ti with nvidia drivers 419.35

perhaps something useful : ExportScript.Config.FirstNewDataSendCount = 1000 Stutter even if Ikarus is not started ! ExportScript.Config.FirstNewDataSendCount = 1 Stutter only if Ikarus is started

Thanks for your help, my answers in green :

Ok, i've checked every single line in F15C.lua (\Scripts\DCS-ExportScript\ExportsModules), with no result. The only way to get rid of the stutter is to delete allmost everythings... I can't find the culprit so far But I am really noob regarding lua scripting (regarding scripting in general, to be honest). Is there something else to check with DCS ExportScript ?

Thanks Klem, actually, I have 4 projectors and 2 LCDs in panorama mode (11520*1080). The 4 beamers use nvidia surround mode to be like one big screen for windows. This setup works well with my first sim. Everythings is almost the same regarding my two sim apart from the CPU, the GPU and the motherboard. The weird point is that the performance issue appear only with the more powerfull computer ! I will follow McMicha advice and check if there is something to change within DCS exportscript config files. I allready tested one thing : If I deactive DCS exportscript line within export.lua and run Ikarus, performance are OK ! (but obviously, the avionic screen is frozen)

Thanks for your inputs McMicha, I've tested without frame limiter (graphics.lua or via nvidia inspector). With these parameters, fps range from 55 to 150 FPS with or without Ikarus BUT, without Ikarus everything seems smoother. To be more acurate, when Ikarus is running, visually it's looks like the FPS are halved (even if the FPS indicator numbers displayed doesn't decrease !).

Hi all, I have some difficulties with one of my sim : I use 4 projectors and 2 lcd display. One of the LCDs are used with Ikarus for the avionics. All the screens/projectors are at 50Hz and DCS is also limited at 50FPS via the graphics.lua file. I have no problem with my first sim (Core I7 old generation with 1080TI) but, strangely enough, I have performance issues with my second rig (tested with two computers : Core I7 8700K and AMD Ryzen 2700X and 2080TI) : Everythings run well at 50 FPS until I run Ikarus ! When I run Ikarus, MSI afterburner or DCS are still telling me a solid 50FPS framerate but I clearly see a lot of lag and stutter on the 3d view (projectors). When I close Ikarus, everything run well again... Precision, I use the same config files/parameters on both simulators. Any idea ?

Has anybody try DCS 1.5.8 with the last windows 10 update ?

Hi all, Today I reinstalled DCS 1.5.8 on a new PC with a fresh windows (pro 1809). DCS doens't want to start ! It's look like it's due to the visual studio redistributable packages. On the same windows, DCS 2.5 works fine. On the same PC but with windows 1803, DCS 1.5.8 works fine... Any idea ?
