Starting from C&D mode and moving resets the navigation

[YoYo]

DCS 2.9.21.16552, I know there was nothing in the changelog, but the bug still exists in this version.

[YoYo]

Any news on whether this issue has been resolved in the test environment? This freezing and resetting issue is quite annoying.

The issue was reported quite a long time ago, around the release date, and we know where the cause lies from the user level.

Confirm. The problem remains to this day. It occurs on all maps, no matter what launch.

After the last patch the workaround starting just on the battery no longer works. The hesitation/Freeze and Reset of Nav sys now happens every time.

Unfortunately it’s still present. Any heads up on this ED? @BIGNEWY?

[Typhonus2]

I'm having an issue that feels related to this one.

When I fly the Mig, I experience a significant frame rate drop compared to even the most demanding aircraft. The f-14 or F-4 give me 140 FPS on the exact same map, mission, and placement as I get 114 FPS with the Mig. And I get stutters in the air which I don't get with any other aircraft under the same conditions.

Hot starting on the runway, in the cockpit I hear this slight clicking sound on my right, like a button being repeatedly pushed.

The major symptom is that the WP/AD buttons don't function properly. Button 1 is illuminated to begin. But if you push Button 2 or 3 they illuminate very briefly, and the HSI upfront begins to switch to the range to their respective waypoint, but then Button 1 depresses on it's own again and resets it to one. I've checked key bindings, and literally nothing is bound to any of those buttons. I have to change them by clicking in the cockpit. It does this no matter how I alter the flightplan, or if I used the DTC. The nav system is basically unusable.

Is anyone else experiencing this?

3 patches and no fix for this? Guys...!

Clicking on the navigation panel might be related (and is a symptom of the unresolved issue this thread is about), but I don't think so about the rest. What you're describing here is something else, I think. Personally, I don't have any problems with FPS drops; the only FPS drops and lag occur when running the MiG-29 in C&D and using the GPU. Now, it's noticeable even without the GPU. 

[Typhonus2]

Don't know. It sounds like something invisible is actuating the panel somehow, and that its location is somehow indeterminant - like an invisible finger that may be moved by resolution or something. And that somehow the repeated actuations are eating frames. But I don't know. Sadly, the plane is unflyable for me as it stands. It worked when I bought it, so it's something that occurred between then and now. Every patch for this game just seems to create five new bugs for the five old ones it fixed.

[AeriaGloria]

I’ve only noticed lag from one thing, locking in IRST search mode 

[Typhonus2]

Can you think of any reason why the waypoint/AD buttons would just keep going back to 1, no matter how many times you clicked the others?

Bug 

[BIGNEWY]

Navigation button issue in this patch has been reported the team are working on a fix. 

work around recommendation is to program all 9 points (AD/WP/BEACONS). This might solve the problem for now. 

 

[Typhonus2]

Programming all 9 in the DTC did work, although it's a bit unwieldy. Thanks. I also solved the FPS problem I noted above, so I think they're connected. As soon as I did this fix, my FPS jumped back to the 140 all my other modules get in this place.

[YoYo]

The question is whether this solves the GPU connection issue and the navigation system reset when starting Cold and Dark, as this thread is about a different problem that may have just gotten worse. I won't be able to check this until next week.

No. You still get the taxy Hesitation and reset, but now you get it all the time even on a Battery start.

[YoYo]

I will do this test with 9 programmable buttons today and let you know on my side as well.

Niestety błąd ten nadal występuje w obecnej wersji DCS 2.9.21.16362 .

Nadal się zawiesza i resetuje panel nawigacyjny. Proszę to naprawić, dziękuję.

 

I also confirm that the same error still occurs
