Now with the new version i have with same settings and addons (only orbx) many drops framerate whit change view and i see blurry textures. I use original prepar3d.cfg with only 2 edit: OPAQUE_SHADOW_TEXTURE_SIZE=4096 (defaul 2048) LOD_RADIUS=9.5 (default 6.5) I use very high settings 4K (almost maximum) but with v4.2 work very well (without blurry), min 30fps max 60/70fps, with 4.3 drops min 18/20fps and i see blurry!

  3. Hi all, minor annoyance but does anyone know why some addon aircraft load from start screen with engines running and then the engines immediately shut down? Realair legacy does it, carenado Navajo does it. I don’t have any mods for cold dark or any flights saved in these conditions so I’m at a loss really.

    This is getting me stumped in a big way for the last few days trying to figure it out. After switching from fsx to p3dv4 version so far this has me stumped. Issue is that with fsx I had set my default start up screen to be my own airport or town where I live eg Melbourne. Than when ever I change location to any part of the world the time will reflect on the change, but for some reason p3dv4 is staying the same time where ever I go, also I notice after when I select change airport the restore time on the move iam unable to untick or tick its checked now. The other night I was a…

  9. Hi, this has been something that has been annoying me a bit. Does anyone have any suggestions on how to do ground steering except the regular combined ground steering + rudder? What I want is for example: when on ground the spoiler axis = ground steering but when in air spoiler axix = spoiler. How do you guys do ground steering and clever solutions? I think its really annoying to do the ground steering with pedals. My setup is Saitek rudder pedals and a Thrustmaster Hotas Joystick. Thanks for any suggestions /Niklas Eriksson

    Hi Folks, I’ve been using Tomato Shade for a couple of months with no issue but today I had an issue with Windows Defender thinking that the “DynamicReflectionMaker.exe” file is in fact a Trojan. Defender keeps quarantining the file and removing it from the Tomato Shade folder. Has anyone else had this issue? I’m running Windows 10, P3D V4.3 and Version 23 of Tomato Shade

    Hi all, anyone have some input on the F1 B200 in v4? Really considering getting this as the Milviz 350 seems to be taking an eternity 😉 Looks like F1 added some features and recompiled specifically for v4. Really interested to know if the G1000 screen(s) is still heavy on the sim performance? i know F1 has the refund option but would still like some feedback first. Thx

    I recently installed this add-on and find it dfficult to fly. When I push an anti-yaw pedal nothing happens to the yaw - at first! Suddenly yaw changes and then continues alarmingly. I then have to stand on the opposite pedal and the same thing happens in reverse. I have reduced pedal sensitiviy in settings with no improvement. I know that the fenestron gives different handling than an exposed tail rotor but this seems more like PIO. I emailed MP Design Studio yesterday but no reply yet. Any ideas anyone? Thanks, Brian

  14. I often read that limiting the framerate in P3D V4.3 has benefits - for me it only kills framerates. Let me give you an example for the same scenery, being static on the ground (let's take LOWW for example): Unimited framerates result in app. 40-50fps Framerate limit to 40fps results in app. 25-30fps and choppiness Framerate limit to 30fps results in app. 20fps and choppiness Framerate limit to 20fps results in app. 12-15fps and choppiness Why? For me, limiting the framerate has no benefit at all...

  16. On Sunday I made a post recommending BJ Marten's "Cold & Dark to Taxi Ready" videos on YouTube. I had recently discovered them, thought them to be excellent, and wanted to call the community's attention to them. Today this post returned to the front page as others favorably commented on the post. But soon after these comments, the post disappeared without any explanation whatsoever - or even notice to me. What seems to be the problem? Robert

    I am using the R22. I have followed all the instructions. I think. I can display the autopilot and adjust everything. All the buttons seem to work "AP" etc except YD. But when I lift off the copter spins/rotates to the right. The peddles don't stop it as they would without the autopilot. I am using the GTN750 with an active flight plan. Every thing set to GPS, NAV on. Does not follow the flight plan. I've posted this in the other post on this topic but had no reply's. What am I missing. P3d V4.3 Thank You. Bill McCracken

  20. Few days ago F1 released new GNS (2.04) for P3Dv4.3, but seems to me that import flight plan dosent work. did You notice the same problem? According the manual: After powering up the GNS and acknowledging the “Database” and the “Instrument Panel Self-Test” page by pressing the ‘ENT’ button twice, you will see the “Import Flight Plan” page. Turn the right inner knob to choose your flight plan but I havent this screen Import Flight Plan (tested GNS 430).

    Hi... I recently completed a flight from KSFO-KDFW. When finished, I shut down P3d. I was looking to see if PSP was installed and noticed there was an update to Open LC or Base that I needed to install. I went ahead and did the install/update. When I did that, I tried to load P3d and the sim just hangs in the black start screen. I don't get a CTD or any error message. It just sits there and never gets me to the menu screen. I can only think the update is what is causing the issue. Can someone point me in the right direction to fix? I'd hate to have to do an uninstall/install because I have so many add ons in there.
