You are probably right because I think I read somewhere the physics simulation runs at 50Hz in KSP. I assume something has changed regarding this matter between 1.5.1 and 1.9.1 because I'm not limited anymore. I can have spikes at 3000 RPC/s no problem.

Hi, I'm using kRPC 0.4.8 on KSP 1.5.1 and I was wondering if it was possible to modify the RPC Rate. I'm stuck at 50 RPC/s. I tried to modify the advanced settings with no luck. I'm using the Java client. Thanks EDIT: Works fine on 1.9.1

Thanks ! The solution is to set windows resolution to 1080p everytime i launch ksp in windowed mode. I also added the command -popupwindow to play in borderless. It might be also working en fullscreen but i prefer borderless. It's the 6GB version. I bought the 4K version essentially to watch Netflix or any 4K content but not to play in 4K. With that said though, i can play some titles like skyrim in 2K (and with mods ! ) or Metro 2033/LL.

My script works but for an unknown reason my reference pitch is 12° below 0°. If i want to pitch to 7° i have to write 19...

Thanks for your response ! I eventually found what the issue was. My screen is UHD but when i play in fullscreen even if i set the resolution to 1080p the game is rendered in UHD. So the solution is to play in windowed in 1080p. It works fine but the game only take 1/4 of my screen. I tried everything to upscale it to UHD in 1080p but it doesn't work.... I'm open to any suggestion

Hello, I'm trying to improve an old SSTO autopilot but it doesn't work and i can't figure it out why. Here is my script : CLEARSCREEN. BRAKES ON. SET LOOP TO TRUE. SET THROT TO 0. SET Y TO 0. SAS OFF. RCS OFF. CLEARSCREEN. SET STEP TO "Ignition". function display { PRINT "Altitude: " + SHIP:ALTITUDE AT (15,4). PRINT "Speed: " + VELOCITY:SURFACE:MAG AT (15,5). PRINT "Apoapsis " + APOAPSIS AT (15,6). PRINT "Periapsis " + PERIAPSIS AT (15,7). PRINT "Time to Apoapsis: " + ETA:APOAPSIS AT (15,8). PRINT STEP AT (15,9). PRINT Y AT (15,10). PRINT SHIP:BEARING AT (15,11). } UNTIL LOOP=false { display(). LOCK THROTTLE TO THROT. LOCK STEERING TO HEADING(90,Y). IF STEP="Ignition" { SET AG1 TO TRUE. SET THROT TO 1. BRAKES OFF. SET STEP TO "TakeOff". CLEARSCREEN. } IF STEP="TakeOff" { SET Y TO 7. } } Actually my problem is the LOCK STEERING. It lock the steering indeed but not at the right pitch. I made another script in which it works so i don't understand what is happening. Thanks for your help.

It is the Dell 7577 if you want the reference so the cooling is ok + i think i'm not even at 100% on GPU nor CPU while in game. Everything is updated so i don't know.... I have no trouble in any other game.

Thanks for your reply. I'm already on maximum performance and i play whille puggled. I don't really know what the issue is.

Hello, I just bought a new laptop and wanted to play KSP but it seems that the fps are lock at 30 even with V-sync Off and frame limiter to 60 or even more. I get a steady 30 fps in menu and like 20 fps in game. I went to the Nvidia control panel and the game runs on the gtx 1060. My specs are i7-7700HQ, GTX 1060 Max-Q and 16 GB of DDR4. Thanks for your help.

Pls can someone help me ? It runs fine on a pc with i5-6500, 8 Gb of ram and a rx 580 (and with mods). I don't understand why i have like 20 fps on this one. I don't have problems with other games. Thanks Specs : -i7-7700HQ -GTX 1060 Max-Q -16Gb DDR4

Ok I'll try it thanks. But it is still strange that i get only 30 fps in the menu. The only mods install are the followings : http://prntscr.com/krdn5k EDIT : I disabled PlanetShine and gained like 5 fps so it might be a performance issue and not just a frame limitation like i tought but i don't understand why. My specs should be enough to have at least 40 to 50 fps.

Sorry for late response. thanks for your explanation, i will try to find an average terminal velocity and see if it works That's a typical kerbonauts response but not what i'm looking for lol

I have heard of this mod and it looks cool but i think it might be even more difficult to simulate it in Excel lol I'll give it a shot anyway and see what i can do. If i find the terminal velocity, i may be able to do something like this in excel : If velocity>terminal velocity and altitude>X use terminal velocity This may be working when trying to recover the rocket even though it probably won't work in others case scenario. EDIT :I tried from 40000 m and i never really reach terminal velocity, i indeed lose a big amount of speed at around 10000m to reach something like 200m/s and then i continually slow...

Thanks for your replies I didn't know that Maybe this will help you to understand what i wanna do : https://prnt.sc/jmj8l8 In this exemple i start at the launch pad which is at 80 meters and i want to stabilize at 1000m. Here the drag isn't really important but it is if i want to start at 40.000m and stabilize at 110m for example. I have to tune the K,Kp,Ki and Kd values in order do what i want. This "simulation" helps me to do that. So if i don't include the drag i might start the burn too early because i'll be assuming that nothing is slowing me. I know there are other (smarter) ways to recover rocket with kOS but i want to try this.

I think i'll go with the table then, thanks. I know, with speed comes heat, so local pressure will vary, so do locale atmosphere density and i think i wont be able to include that in excel lol . What i want to do is an approximation of this while being as precise as i can in the limit of my knowledges. Yes i want to know how it works in KSP in order to make my "simulation" the more accurate possible. My goal is to recover my rocket, SpaceX style, using kOS. (Sorry if my English isn't good)

Ok i'll try this thank you. I presume this will also work for airbrake. Last question : is there a way to have the equation of the athmosphere density ? I found the table on the wiki but no equation. I can manage to do something with the table but i would rather have the equation.

So what do i do ? I'm a little confused. The widest point being the protective shell, can this works ? And i take a Cx of 0.21 ?

ok thank you I'm using a protective shell so i'll just assume that it's a cone of x meters height ? https://prnt.sc/jlum0j Actually i'm trying to get the drag force because i'm coding a hoverPID in kos, i just go to 500m and get stable for example. I made the modele in excel and everything is ok as long as i don't need to go too high otherwise the drag force is too high and i have a big difference for the first overshoot in my step response for instance. So i need to include the drag force in the modele.

So if i want to estimate the drag force of my rocket i'll just take a Cx of 0.21 and put it into this formula in excel and that's it ? EDIT : I just realized that i don't have the surface area either.....

Hello everyone, i'm new here. So my question is simple : How could i get the drag coefficient of my rocket ? I want to have the equation that gives me the drag force of my rocket. I found the equation but dont know how to get the coefficient. Thanks for your replies
