Ok, I also have posted it in the DCS World 2.5 bug section.

Hi, just found this bug within the first (initial) mission of the F-14 Zone 5 Campaign, but it is a general DCS bug, I guess: The ground crews are looking like ghosts (but only the guys in blue overalls and basecaps). In daylight they are looking normal. Best regards, Rene

Hi Tomcatters, not sure whether it is a bug of the campaign or of the DCS ground crew rendering. After landing on Nellis AFB during the first (initial) mission I saw this: In daylight these ground crew men are looking normal. Best regards, Rene

Hi Flappie, I tested again and I am pretty sure now, my graphics glitch has the same source like the strange graphics glitch (yellow, red) in this forum. My setup contained two M163, four Mi-8 and a Humvee as observer. Graphics glitch Mi-8 02.trk Here is a video of it: (the first 5 pictures were taken from a run yesterday) Then I changed the setup. Instead the Mi-8 I used Bf 109K-4 and there was the same glitch. Here is the video: The only differences were the colours (grey/white instead darkgrey/black, red/yellow instead black/blue). Also the shape was very similar (looks like a cone in some of the pictures). And all these glitches are not longer than 1 frame. That means, on my rig with my settings (rock solid 60 fps) it is only visible for a 1/60 of a second. If you run DCS with a higher frame rate (90 or 120 fps) than it would be visible for only 1/90 or 1/120 of a second. It is possible that you just overlook it. Best regards, Rene

At least the second crater is still there (found it by random). I mean, that's an enormous crater and maybe the digital workers of ED only have some virtual shovels to fill it in, but three years are a really long time to fix such a bug.

I also had these orange and yellow flashes together with black and grey flashes in non-WWII modules, see here: The orange and yellow flashes were gone someday. I thought because of a DCS update or a graphics driver update. The black flashes stayed. I hope you are right and my graphics card is not dying, because then DCS would be history for me at least for the next six or more months. It is almost impossible to buy a new one (no matter whether AMD or NVIDIA), and if, you have to pay moon prices.

Hi Taz1004, my glitches are also just very short flashes, not longer than 1 or 2 frames and happen in very limited situations. When a graphics card dies, then these glitches are longer or persistent, are more randomized and don't happen in exactly the same situations. My card is running within normal temperature ranges and isn't overclocked. On weekend I will dust it off and give the underclocking by AfterBurner a try. Thanks for your help so far. Best regards, Rene

Besides of the colours this glitch is similar to the glitch in this topic: There are also very short flashes in wrong colours. Do you think it also is caused by a failing GPU? Unfortunately turn of automatic undervolting didn't help.

Hi Flappie, attached you can find the dcs.log. @Taz1004 currently my card runs with automatic undervolting. I could try to turn it off. But when my card is failing, why I only see this glitch in situations when an aircraft/helo starts to burn (on the ground/in the air doesn't no matter)? A burning truck, house, ship whatsoever never causes this glitch. And also in other games I don't have any glitches or other graphics issues. Best regards, Rene dcs.log

Hi Flappie, I don't have a NVIDIA card but an AMD card (RX5700 XT). Is there a similar folder for AMD? Best regards, Rene UPDATE: I have resetted the shader cache in the AMD Radeon settings (Global settings -> Reset -> Shader cache) but it didn't help.

Hi Flappie, I see the same glitch in your track. I disabled all mods, executed a cleanup and a repair including the options "Check all files (slow)" and "Search for extra files after repair" and I also deleted the fxo and metashaders2 folders, but without result. The glitch is still there (see pictures, captured from your track). The strange thing is, that the glitch is sometimes there, sometimes not or the intensity of it is different when I run the track. For example, the both glitches in picture 1 and 2 appeared only in a few number of track run-throughs, but the glitch in picture 3 appeared in every single run-through, sometimes more intense sometimes less. Best regards, Rene

Hi, I just found this bug in the rendering of the F-14B Jolly Rogers Livery (Is it know already?). The right side of the Tomcat is black (or very dark grey). If I zoom out, then it looks normal. Map was Syria. Best regards, Rene

In my opinion this issue is similar or identical to the glitch I found (besides of the colours): It happens almost every times when an air target is hit, no matter if it is on the ground or in the air. Ground objects/units or ships are not affected (at least from my expierence). It is not related to: - the new damage model for WWII (I only fly modern aircrafts) - the type of aircraft/helo (flown or hit) - the map (I see this on Caucasus, Nevada, Syria and Persian Gulf map) - the distance to the target - the angle of view - the view position (internal, external, ...) - the graphics card (Nvidia and AMD are both affected) - the version of the graphics driver I think it is caused by the rendering of the fire, flames and smoketrails of hit planes and helos, which was improved by ED several months ago. Since this update I expierence this issue. In the first months the colours were also red, yellow, orange (but also black or grey in some cases). Now I only see these black and blue (sometimes also white or grey) glitches.

Hi Flappie, hi Bignewy, here is an update to the issue I found. Attached you can find a track with a lot of black flickering (CBU-97 hittings, APKWS hittings, GAU-8 hittings). There are also some screenshots captured from a video of the same mission. The flickering appears only when I hit the Mi-8's on the ground. Hitting the fuel trucks with APKWS and GAU-8 doesn't cause the issue. For me it seems to be related to the flames of the helos. It's just a test mission to demonstrate the issue, so don't judge my flight performance too harshly. Best regards, Rene Black and blue flickering.trk

Hi Kevstosmart, sorry for my late answer. I didn't change back to an older driver. I used the 19.12.1 Radeon driver for a long time. After I ran into the described issue I tried the 20.9.1 WHQL driver but with the old Radeon GUI (not these Adrenalin GUI crap) because I need the Frame Rate Target Control setting, which isn't present in the Adrenalin GUI anymore although the function is still existing within the drivers. With the 20.9.1 driver and the increasing of the DRAM voltage the crashes are completely gone. I didn't try the newest WHQL driver (20.11.2) yet, You know, never change a running system. Best regards, Rene

Hi Flappie, actually, when this thread came up I had the same orange and yellow flashes like described, together with these black flickering. The orange flashes where gone sometime (maybe because of a DCS or a graphics driver update), but the black and grey flickering stayed. If you say that's two different glitches, then I am glad if my track can help to fix it. Thanks to Bignewy for opening a new thread. Best regards, Rene

Hi Bignewy, hi Flappie, I flew a test flight in an F-15C on the Caucasus map to demonstrate the graphical glitch (track attached). There is black and partly light grey flickering after the Su-24's are hit and going down. It seems it is caused by the smoke trails (black and light grey). Best regards, Rene Testflight Graphic glitches F-15C Caucasus.trk

Hi Jim, thanks for the hint, but Enhanced sync on or off doesn't make any difference (I already tested it and tested it again now). I am using Enhanced sync for a long time and never had problems with it in DCS. I am experiencing the described slightly stuttering during head moving only since the DCS 2.5.6.57264 Open Beta update. Best regards, Rene

The only WWII module I own is P-51D (but fly it very rarely). I see the same flickering in modern aircraft modules like F/A-18C, F-15C, F-16C, Su-33, MiG-29, Mirage 2000C and so on. I don't have a NVIDIA graphics card but an AMD card with the latest recommended driver. I saw this flickering already with the old 19.12.1 driver (maybe a little heavier), for the very first time at the beginning of September this year.

Hi Flappie, I see a black flickering at the beginning of the track (short after some of the planes have crashed into the ground), which only affects the sky (means, the whole sky from the horizon upwards is flickering black for about one or two seconds). I see another flickering (grey in this case) when your plane flies through the smoke columns, but this flickering effects the whole cockpit (or even the whole field of view). Best regards, Rene

Hi BIGNEWY, all my relevant tracks they could show the issue are corrupt, what means, if I replaying them I am flying like an idiot and crashing into ground (nothing of this happened during the real flight). If ED wants us to send tracks to investigate issues, the tracking system should be fixed urgently. Best regards, Rene

Grahpics Card: Sapphire Radeon 5700XT Nitro+ SE Graphics Driver: Adrenalin 2020 Edition 20.9.1 (Recommended by AMD) I see this glitch only in correlation with explosions of aircrafts (missile hits, crash into the ground) even if the target aircraft is hitted or crashing BVR. Sometimes it's a yellow flashing, sometimes a gray/black flashing, probably caused by a corrupt rendering of explosions, flames and smoke trails of the hitted/crashing aircraft. I guess it came together with the rendering improvements of fire and smoke. I will try to upload a track if I find one which isn't too large.

Hi Flappie, just for your information. The last two weeks I flew several missions in different aircrafts (A-10C-II, AV-8B, F-15C, F-16C, F/A-18C, Su-33) with mission durations between 45 and 90 minutes without any further CTDs. It seems the solution for my issue was a mix of graphic drivers update and DRAM voltage increasing. Best regards, Rene

The same as mine. Just a slight stuttering and only during head movements without any impact to the frame rate. The stuttering in the video of Guppy is very heavy.

Here there are two tracks they (hopefully) show the issue. The first one (F-16C Caucasus) shows the slightly stuttering by using DelanClip headtracker. The second one (F-15C Nevada) shows heavily stutters by using the mouse for view steering. In the first case the frame rate is between 60 fps and 41 fps (over large forestry areas) without any stuttering as long I look straight ahead or to the side without head moving (in flight). As soon I move my head there is a slightly stuttering without any impact to the frame rate. In the second case the frame rate is rock solid at 60 fps. As soon I move the mouse there are heavily stutters also without any impact to the frame rate. F-16C Caucasus Stuttering with Headtracking.trk F-15C Nevada Stuttering with View steering by Mouse.trk
