  1. Just out of curiosity how does the 737-300 perform when it is lightly loaded? I have found in the sim that with about 1,000 pounds of payload I climb out at just over 5000fpm initially and reach FL370 in just under 15 minutes (unrestricted climb). Is this pretty accurate in terms of real world performance? I'm sure there are occasional flights where there is little to no payload (at least for the 737 cargo aircraft).

    This was brought up in an earlier thread and actually is in the Cirrus POH/Flight Manuals as well as the TorqueSim version of the POH included with the plane. 

    My response from the earlier thread is below.  I've not found yet what is proper procedure from pilots more knowledgable than me.

    I'm not a pilot, just a newbie flight sim guy (since late May 2020) who really wants to fly the TorqueSim SR22 "by the book" as they say.  So, I bought a digital version of the Cirrus Flight Operation Manual for the SR22!  Here's a quote from the book about this issue:

    “During the first takeoff of the day in an SR22T or SR22TN, due to relatively low engine oil temperature and associated higher oil pressures, engine manifold pressure may exceed limits. This is acceptable, but if this occurs, pilots should smoothly reduce power to bring it back below red-line. In subsequent flights with higher engine oil temperatures, verify that the power lever can be moved to full forward and remain within limits. If not, then the system should be adjusted.

    Maybe one of the SR22 pilots can comment further.  I've been reducing power, typically all the way to manifold pressure of 29.5 (it still shows yellow at 29.6).  I've not found a source yet that talks about how far to cut power back (just to yellow or all the way to green).

     

    Okay thank you so much. 

  3. I am still running into this issue even though 11.5 is now final. I went through and made sure all of my addons are compatible but it appears I only get this camera stutter with the TBM. It is especially noticeable when zooming in and out with the mouse wheel. There are half second pauses when I zoom in/out. I originally thought it was related to Gizmo, but disabling the plugin makes no difference (other than render the aircraft unusable obviously).

    There is a lot of calculation going on behind the scenes when you run the IXEG 737 - and with the base simulation becoming faster and more smooth, this calculation (naturally causing lag) is becoming a bit more appearant. In the past the emphasis was on causing "less total load" on the system - so you would run some operations only every 5 seconds, instead of "every flight loop". This would allow to keep the general framerate up, and small dips did not "stick out" very much in an already fairly slow and stuttery base simulation.

    Now with Vulkan allowing faster and really smooth framerates, calculation delays cause these observable stutters.

    Ben is continuously working on evening out the load placed by these computations by improving Gizmo, and we will also have to look into our code and decided if we need to "spread out" things more to get a more smooth load - at the cost of diminishing framerate.

    If you look at other add-ons of comparable complexity (I am not talking a small Cessna or TBM here) you may also see either a more choppy rendering or a fairly diminished framerate compared to "default" aircraft.

    We strive to make things as smooth and fast as possible - but naturally we need time to adapt to the post-OpenGL situation.

    Cheers, Jan

     

    Thanks for explaining it. Is there a reason why the stutters are more noticeable on the ground? Once I takeoff I don't really notice it. Maybe less detail rendering or something?

    There is one more thing you can try - switch off the WXR SYSTEM switch (found between the two CDUs).

    Some meshes have a very high count of elevation points - our weather and terrain radar scans these elevation points at regular intervals and we had reports of those causing "code slowdown" every few seconds.

    The other question is: What kind of framerate are you getting with OpenGL and with 11.50?

    Cheers, Jan

     

    Ok I'll try that. Frames with 11.5 have been anywhere from 40-50FPS. I haven't used the OpenGL version in awhile, but I recall the FPS being closer to 30 when I was using it. Frames are really good I just need to figure out the stuttering issue that is happening in 11.5.

  6. I am also having some issues with stuttering as well. Tried some of the solutions listed above, but I haven't had much success. GSync is on and I removed XPrealistic but I didn't see any performance difference when it was installed to begin with. I also tried messing around with the garbage collector feature and that helped somewhat, but the stutters are still quite prevalent. Should I try rolling back to 11.40+ instead of Vulkan? I understand Vulkan is supposed to help with the stuttering, but it is also still in beta so I am not sure how much stability I can expect from it or not. I tried both versions of Gizmo, but for me personally the performance was the same with both versions.

    ...and I just doublechecked as I saw your post on the .org - my floodlights work fine with 11.50r3.

    Cheers, Jan

     

    I think I fixed it. I thought I deleted everything in my preferences folder the first time, but I must of missed something. Thanks for the help.

  8. Yep HDR is on. I disabled all plugins, scenery, and deleted the shaders folder and ran a test again. Unfortunately the domelights still aren't working. The lightbulb itself turns on,  but there is no indication of the cockpit being lit up. I am not sure what is causing this. Should I try a complete reinstall of the aircraft and Gizmo? Maybe something wen't wrong with the install or something. I'll attach my log file below as well.

    Hi sho,

    it could very well be the problem - especially now with Vulkan in the picture. Please try to run without the light mod and let us know if that helped?

    Thanks, Jan

     

    Ok just restored the lights.txt and even disabled reshade to be safe. Looks like things are a little brighter, but the panel lights still seem much more dim than they used to be. At least that is my observation.

  10. I am running into the same issue. With regards to light scripts,  I do have the TK light mod installed. This affects the scenery night lighting and modifies the "lights.txt" file. I have used this mod with the ixeg 733 in the past without issue, so I am not sure if this is the culprit or not.

  11. Same issue here. When I pan to the sides it is very jerky and FPS drops by 10-15 frames. If I turn reflections off, this helps but so far I haven't run into this issue with my other addon aircraft yet. This is with running Vulkan. Also on the compatibility list, I noticed I have XP realistic installed, but I haven't noticed any issues within the sim.

    I would think that the "feeling" of flying the 737-300 and the NG (at the same weights) is pretty much the same - not having flown the NG in real life. I know that our 737 feels exactly like the 737s I flew in real life.

    Our VNAV is likely not as refined as the one on the PMDG. It (and some other FMC features like HOLDS, PROG page,...) is slated for improvement but was never really completely working.

    Here are two threads I made specifically for prospective buyers and to get new customers up to speed on the current status:

    Cheers, Jan

     

    The aircraft is far more usable than it was initially that's for sure. The VNAV thing is a small issue for me as there are other ways to plan a descent if needed. The immersion factor and sounds are by far some of the best I have seen in flight sims though!

    Hi,

    yes, the sound of the engines is realistic - when we got noise cancelling headsets in our cockpit I always slipped them off my one ear during take-off and landing so I could hear the engines better - especially during approach I found that it really helps if you can hear the engines wind up and down. During cruise it really helps to have those headsets, though - the airconditioning (and airflow at higher speeds) is really loud. Note that we have a preference slider for the aircon sounds - a lot of people are bothered by the sound (I wish we had that slider in the real aircraft, too!!)

    The airflow from the packs will modulate with the bleed pressure available. There are basically two spots where bleed air gets drawn from the engine, one is called the low-pressure bleed (5th compressor stage) and the other is the high-pressure (9th compressor stage). The modulating and shutoff valve controls how much high-bleed air pressure gets drawn - it opens during low engine RPM to allow more high pressure air, otherwise the bleed pressure would drop too much and you would have a problem supplying the packs and/or anti-ice systems during high altitude flight and idle power, for example.

    When you have the engines at idle, this valve is pretty much fully open - now the engine RPM governs how much bleed pressure there is (you can see this on the pressure indicator, too). The airflow is a function of bleed pressure, so at idle it will modulate with the engine RPM. Once the pressure gets high enough, that little valve says "ok, this is enough pressure, I am gradually closing now" - and you can see the pressure stay static at that point, even if you increase RPM further.

    Cheers, Jan

     

    Wow thanks for the detailed explanation on all this! I have flown the NG series a lot on p3d, so having the chance to see a detailed model of a 737 classic on X-plane shows how very different the two generations of aircraft are. This is only based on sim experience, but I am sure the two aircraft feel quite different to fly in the real world. One thing I noticed is the VNAV decent is not quite as precise in the -300 as it is in the NG series. Maybe this is by design? I often have to use FLCH or V/S to meet altitude restrictions.

  14. Hello, 

    I have a couple questions regarding sounds.

    1.) Is the engine roar you hear in the sim what you actually hear in the cockpit of a 737 during takeoff? Realistic or not, it sounds absolutely amazing! That and the extremely loud pack noise which 737's are known for. 

    2.) Is it normal for the pack noise to get louder as you increase thrust? I especially notice on the ground when taxiing.

  15. I noticed that the winglet shape on the IXEG 733 seems to be a little off. It looks like it is too wide at the base of the winglet. I don't mean to nitpick, but it would be nice to have this issue addressed in a future update. Thank you.
