I confirm the test version completely resolved the issue. Very impressed. Great interaction. Thank you.

Thank you, email sent.

OS and PageFile both on SSD as well as TacView and the TacView save file. For the rest of the questions: TacView 1.4.0 Happens in both 64bit and 32bit It's in 21 day demo so full professional I assume. It's not related to any specific flight recording. I can reproduce with no track playing. Source is DCS. I have not used TacView before now so I don't know if there were problem in other version. Video card is AMD 7970. Driver is the most recent full release from AMD (not beta); 15.20.1062.1004 Once it's zoomed in watching the planes fly around and I leave it alone it performs just fine. Problem is only observed when moving the camera around and it seems to be worse the further zoomed out. Launching tacview, no files opened I see the globe. I can zoom in quickly with mouse wheel. While it's zooming in it will have several brief pauses. If I try scrolling around the landscape the scrolling will pause frequently. Again this is with nothing playing, no files opened, just looking at the terrain. When it's pausing the GPU seems to stay around 25%. CPU core 3 is 100%. The other 3 CPU cores have low usage. I also tried resizing the window to be tiny. Figured it may run better with less pixels, but there was no change to behavior. DxDiag_151105.zip

Is it just me or is performance of the strategic view very poor? I'm in the free trial on a windows 10 system. Looking at the strategic view if I press play then try to move the world around by mouse dragging I will frequently get pauses during playback. If I remove the terrain it's a little better, but I do still get pauses. The saved file is on an SSD drive. I'm trying with a saved file, without dcs running, so it's not being written to. Processor idles around 15%. GPU jumps up as far as 75%, which already seems high for such simple graphics. Using latest release of tacview, 1.4.0. Edit... Best I can tell it spikes a single processor core to 100% then gets really bad frame rates for a short time. Eventually it recovers until you move the view around again. You can see the behavior with no saves loaded, just zooming into and around the earth that is visible with first launch of tacview. When watching the scene play the performance seems to be worse for angles allowing you to see more terrain or with zooming out further.

You can change audio settings in game, like cockpit volume or world volume. But the settings have no effect until the game is exited completely and restarted. To reproduce. Launch, jump in a mission with running jet. F2 to listen to level of engine sound. Quit mission, alter world audio settings (reduce/increase). Restart mission and F2 again to listen to engine audio level. No change. Now exit completely, get back in, back into mission. F2 again and you will see the audio change is now effective.
