Stress test on GPU give me no blackout. Unreal environment gives me no problems. All OpenGL apps work great. I load cached voxels, cached liquid meshes. I have Renderman XPU GPU, Arnold GPU, Vray GPU. I tested them all in GPU only mode with stressed scenes. no blackouts. Google Earth with all options ON runs without error in Chrome and as stand alone Earth Pro. I run Earth in DirectX. With DCS, when I have a blackout, on Task Manager GPU 3D graph, the 3D usage graph, which is normally at 98% and 6-7.8 GB of GPU Memory in AH-64D, goes flat to zero on both. Stays there for some seconds. Sometimes its a flash, sometimes its 5 seconds. Rarely 7+ seconds . Then returns to normal. DCS continues running. No crash. Like DCS is not aware of the blackout. So issue appears to be at driver/hardware level , independent of DCS. DCS hands off display data to Nvidia drivers, the drivers tell GPU to send signal to monitor. I believe that's called Nvidia Hardware Abstraction Layer or similar. It depends on driver. I tend to install the latest Nvidia reference form Nvidia. I do not install Nvidia app. I do not OC. On more then one occasion, I followed Jay2Cent instructions on fresh Nvidia install. Uninstall current Nvidia, clean out Registry, restart Windows with generic default video driver (in safe mode). Fresh install of Nvidia drivers. Restart Windows. The process works, but makes no difference in Nvidia GPU performance in DCS, and other apps. I tried running DCS without YouTube running (on another panel). No difference. Tried running DCS without Chrome or any other browser. No difference. Blackouts are just a minor nuisance. Or not so minor depending on circumstances.

No. I use Studio drivers. For stability and compatibility with DCC. DCS is only DirectX(?) realtime app I have. On my rig, game driver or studio drivers have no benefit or degradation for DCS. Performance is same. Rest of my apps use OpenGL or Nvidia GPU rendering . Going by YouTube, if others are having blackouts on particular drivers, so do I. Except theirs are worse, more frequent and appear under AAA 1stPerson or 2nd shooters. For most part , according to experts (Jay2Cent, Linus TechTips, those fat guys) it is interaction of driver revision, GPU and , often, Samsung monitor. Something with high FPS and high refresh. I notice that there no FPS benchmarking for DCS on YT among gamers. They use first person games. CyberPunk 2077, Red Dead ##, etc.. Basically, I beleive, Unreal based games using latest features.

I looked at dcs.log in C:\Users\UserName\Saved Games\DCS.openbeta\Logs. There is far too much personally identifiable information in it. I'd rather live with inconvenience, and wait for future improvements. The blackout screen only happens in DCS. Thank you for the offer. Its likely not DCS's fault. It may be in all DirectX games. However DCS is the only flight sim and game currently installed. I removed X_Plane and Prepare3D some time back. YouTube videos by other users point to monitor issues. Mine is Samsung 27" 2560X1440 @ 144Hz refresh, via DirectPort. Sadly switching ports does not resolve. Problem does not occur in Unreal, or any DCC apps (Houdini, Maya, Blender, NUKE).

Its not a crash. DCS keeps running and flying. But for the heart stopping 5,7,up to 10 seconds the screen is black. Sound remains. Upon recovery one must determine aircraft attitude and SA quickly.

Had 576.52 drivers. Got 5 to 10 second blackouts in Apache missions Installed 576.80 Studio. Still have 5 to 10 blackouts in Apache. I don't drink or do drugs. But my rig appears to suffer from blackouts when running DCS (latest).

I don't like AA in DCS. Makes instruments blurry. I have it turned OFF. I guess I am better off without DLSS.

No FPS perf difference with DLSS ON/OFF with 3070Ti FE 2560X1440 @144hz. While there are small differences here and there with Apache, A-10CII, Mirage. I see no real FPS gain by using DLSS ON. With latest 2.9.16.10973.1

Add humidity to weather and require DCS level mods to have power reductions due to humidity. Hot & High is not only element that contribute to pressure altitude and density altitude. Humidity contributes also , and effects engine power.

I am not sure if it matters. But sight range is in meters. On hot start , on runway, Quickstart missions, the boresight is not set. I have to boresight on every mission.

Yes. I tried 583.72 Game Ready. Worked fine. However I appear to have somewhat less black screen and black flickering with Studio driver.

System runs fine. Its clean. Runs my DCC software fine. Runs Houdini, Maya, NUKE, Rhino3D, Renderman(CPU and GPU) , Unreal,without problems. In DCS I get 150-180 FPS in AV-8B and Mirage. 120 avg in UH-1 , KA-50, and Gazelle. AH-64D is really my only two digit FPS performer. As DCS is my only game. I judge it against Unigine stress test. Unigine gives 150-180 FPS at 2560X1440 high textures. I get no black screens, no crashes in DCC apps or in unigine, and with latest 583.72 Studio drivers I get intermittent black screen flicker, and mostly in AH-64D.

You make a persuasive argument for ED to tap into talent and experience of RAZBAM in optimizing code. I am glad you thought of it. Credit to you. Great idea! Now, how do we get ED to do it.

Oh wait I forgot. MY opinions have to be popular and favor ED. Darn'it. I just can't seem to toe that line. Oh well. OK, RAZBAM has a team with skills to optimize highly realistic sims to execute faster, to run at significantly higher FPS then inhouse ED teams. The wise choice for ED is pool talent with RAZBAM team. But no, they ED has to be big bear in the cave.

RAZBAM modules are among fastest, FPS wise, in my stable. The worst performing. ED modules. Only exception is South Atlantic. RAZBAM is aggrieved party and I'll stand by them. Thank you very much. Cheers.
