reported Graphics/Rendering issue

[AstonMartinDBS]

During a flight of a self made training mission for the F-14B at Persian Gulf sometimes large black boxes are appearing, at least in the cockpit view.

The issue is rare. During the last flight (totally ~50 minutes) this bug occured only three times within a time frame of 3 minutes. I didn't have any similar issues so far under DCS 2.7 with my other aircrafts.

 

Demonstraton:

 

 

DCS OB 2.7.0.5118

nVidia 466.11

Mission: 510a F-14B AA AIM-7.miz

Track: F-14B GraphicsIssue2.trk

DCS Log: dcs.log-20210430-154000.zip

Hardware: see signature

 

This issue is reproduceable for me. Just fly the mission, climb to ~25k ft and follow the waypoints. The bug occurs usually between WP1 and WP2.

 

Edit: replaced the 18 MB track with a much shorter trackfile

1. repair of the DCS installation
2. update to nVidia drivers 466.27
3. deleting the directories "fxo" and "metashaders2"

didn't solve the problem.

I had this with the first 2.7 patch. It seemed to only happen during sunrise when I went back to get more data the new patch had come out and it hasn't happened since for me, I will see if I can get it to happen again.

 

Also it seemed to only happen when looking through the canopy just left or right of the HUD.

Here's another example with the most current nVidia drivers (version 466.27):

Mission: 000c F-14B GraphicsIssue.miz

Track: F-14B GraphicsIssue5.trk

Log: dcs.zip

Well, obviously this isn't a F-14 specific issue. I've just tested the same mission with the F-16C and F/A-18C and the bug is also present.

 

Mission: 000d GraphicsIssuePGDawn.miz

Track: F-16C GraphicsIssue6.trk

Log: dcs.zip

 

Maybe any mod or admin can move this thread to the general DCS 2.7 bug subforum? Thanks!

just FWIW; this indicates a VRAM issue of some kind (usually). What GPU are you running?

I had absolutely zero problems so far. As I already wrote the issue occurs also with other planes in the attached mission. Probably it's related to a certain mission timeframe (sunrise). I saw this bug first during a flight in the mission 510a F-14B AA AIM-7.miz, shortly after WP1 at an altitude of ~25k ft. As you can see in the captured video the issue occurs only during a period of ~2 mins out of a total of ~50 mins mission time.

In this particular case it isn't, since multiple people started experiencing them after 2.7. They also happen in VR: sometimes left eye, sometimes right eye, sometimes both at the same time.

I see them as well, for example, only during evening/night flights however.
