  2. Start flight
  3. Get in air
  4. See visuals … I tried only daytime

[PC Only] Are you using Developer Mode or have you made any changes to it?

No changes, use for FPS and performance testing

Should check Youtube for TBM cockpit videos, I doubt you would be able to see exhaust fumes / heat blurr at all in flight. I used to fly Beechcraft C90 where you could see the exhaust from the cockpit and I don’t recall being able to see much if any heat blurr in flight.

It is probably like the icing effect, looks cool but it is not realistic at all. I would say, as soon as the prop unfeathers the heat blurr isn’t visibile anymore.

Here is an example of what’s happening both internal and external view:

This topic is very similar to the one I’ve already started, though mine was specifically in VR (where the distortion is really bad).

This must be unrealistic as so much of the extererior view is unusable - the TBM would surely not have received an air worthiness certificate. I’m surprised not more people have complained. The TBM certainly used to be one of my go-to aircraft, but not now.

Hasn’t it always been like that? I agree that it is wrong, at least in flight you definitely won’t see the heat blurr and I doubt you will on ground with the prop unfeathered (except with tailwind maybe). It would be more realistic to have no heat blurr at all on tbe TBM.

No.

It is even worse in flight.

I certainly agree with that one!

In addition to this exaggerated effect, looks like it also affects the FPS as it is the worst airplene I have tried with MSFS 2024, even worst than Inibuilds Airbus.

Yes, the perfromance in the Daher is not good, for whatever reason.

It also badly suffers from the inaccurate windscreen reflections, showing the ground as if the aircraft were made of glass. (Often visible as whites bands crossing the windscreen during take-off due to the impossible reflection of the runway markings under the fuselage.) A lot of unnecessary ray-tracing, so I shouldn’t be surprised if that affects the performance.

• Yes

Provide extra information to complete the original description of the issue:
• The problem is even worse in VR. You actually see the inside frames and corner post between the windshield and pilot door flickering very badly. So, it’s not just an issue with the outside scenery flickering in the exhaust, it’s distorting the cockpit view and mixing it into the outside view also. You don’t see this too much in 2-D, but very pronounced in VR.

Indeed I have the same problem in VR, it is very unpleasant and I think it impacts several aircraft. It’s a shame to go to all the trouble to have a fluid, immersive simulation and have effects that ruin everything.

I read above that it’s not “realistic” couldn’t we just disable it in the options?

Thank you for the bug report.

We have created an internal ticket to see if our team already has this logged, and if not they will attempt to reproduce the issue and create a new bug report. This item is now marked as feedback-logged. If there is an existing bug report or one is created, we will move this thread to bug-logged.

Is there any movement on this?

I would be very surprised if Asobo can’t reproduce it - just take off in the TBM (in VR if possible), at say Queenstown NZ and look out of the side window at the buildings as you pass. Totally screwed up and excessive. FS2020 has exhaust fumes, but at a more reasonable level.

This problem has not yet been bug-logged, so I can only presume Asobo are happy with this? Or perhaps they just haven’t bothered looking?

For what is portrayed as as a “state-of-the-art” flight simulator, this is totally unrealistic (as is also the windscreen reflections in the TBM and many others). If this stays the same when SU2 is released, you are going backwards, rather than forwards.

i mean for half a year, they couldn’t care less that (not only) the TBM still has broken and wrong LOD and fuselage textures, so why would they care for this issue, not only that, look at the other “premium deluxe” planes like the Logitude and CJ4.

I am still getting this problem on the full release version of SU2.

This thread should be kept open till the problem is solved.

About excessive heat blur effect
Solution:
Rename file “FX_Heat_Exhaust.spd” adding something before the name for example. Find the file below
Drive?:\MSFS 2024\Microsoft Flight Simulator 2024\Content\Packages\fs-base-effects\VisualEffectLibs\Asobo\Base\FX_Heat_Exhaust.spd
No more blur effect
Tested during 4 flights VR TBM930 without any problem.
