  1. In real life how do Apache pilots roll or Immelman the helicopter? I am unable to do it in sim without catastrophic results. My helo is empty with 20% fuel. I see Red Bull BO 105 do it. However it has special rigid rotor hub. I see RAF Lynx do it.
  2. 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.
  3. 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.
  4. 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).
  5. 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.
  6. 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).
  7. I don't like AA in DCS. Makes instruments blurry. I have it turned OFF. I guess I am better off without DLSS.
  8. 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
  9. 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.

  10. 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.
  11. Got it! Thank you But really. Three button presses to advance waypoint. Is there a HOTAS bind in controls to circumvent this? Feature request. Navigation commands to AI George CPG. In multiplayer, CPG can handle NAV, while pilot flies. But for single players we have to play both parts.Its too distracting, even with decent autopilot. At 50 GL, pilot can be pushing buttons on MFDs. Guess thats why most armed forces consider military helicoptering as two crew operation. Pilot flying, co-pilot/gunner monitoring(weapons and systems).
  12. I realized that I got vulture circle asswardback. Vultures have keen eyesight. THey use their stereoscopic smell to sniff out a target, then fix eyesight on it. Exactly like a Apache or KA-52. Use FCR/RFI to sniff out a battlefield for targets, then fix them with optical sensors, then go in for feast. Vipers (snakes) are same way. Smell to detect prey, IR/optical vision to fix&track prey location and position for attack. Strike! True predator-prey reaction logic that is used in algorithms in military drones. Now taking the Vulture Turn. By keeping nose or nose gun arc pointed at target, while circling, does three things. All advantageous to attacker. Reduces chances of target fixation. Cause of many CFIT crashes from WWI to both Gulf Wars and GWOT, and few SU-25 in Ukraine. Pilot shalow dives aircraft at target fires guns, but does not pull out, or pulls out too late. Geeggiitte Prevents or reduces distance closure of aircraft to target. Making defensive fire less effective Gives defender more difficult sideways moving target to engage.
  13. You do have to practice, keeping nose, or within gun arc for Apache, while vulture circling. Originated not with helicopters, but with attack aircraft during WWII. Soviet IL-2 pi.ots would form a high circle around German tanks. Then take turns doing strafe runs. When strafing, pilot would slow down to maximize rudder authority, then fire his guns while rudder working to keep nose pointed at target. Skilled A-10 , KA-50, MI-24,Su-25 pilot can do that. I practice it in A-10C, SU-25. KA-50 in DCS. I tried it in MI-24 trial, and it works. You can use rockets and fixed gunpods with this tactic. A matter of skill and practice. Rockets (unguided) are an area effect weapon, so there is no need to physically impact a specific target. Just fire at point on ground, let area effect of warheads do their job.
  14. Thats entirely realistic. Been used since Korean War. Its called a Vulture Turn, or Gun Track (for fixed gun ). You fix your nose at a point and circle around it, with nose pointed at it. When vultures circle a dead or dying animal, they keep their beak pointed at it, as smell is primary sensor augmented by eyesight. Not too different from electronic target tracking in attack helicopters. When working in teams, care to be taken to avoid friendly fire.
