If you buy a new graphics card then you may find your CPU becomes the bottleneck but getting those render frame times will help with any upgrade decision. Xplane is a bit of resource hog but it is getting the Vulkan treatment that should improve things somewhat. Personally I would say you need an absolute min of a stable 30 for proper flight. There are some 3rd party apps that might help such as 3jFPS but they also require FlyWithLua and setting up - these generally change Xplane settings not available in the options menus via scripts such as traffic and LOD settings etc and you can specify a target fps. To do this just temporarily move (cut/paste) your OrbX ortho folder for the region you are flying though when you put it back you will have to rerun Xplane and then edit your scenery_packs.ini file to ensure it has been placed back in the correct order. One way tot est if it is a VRAM issue would be to disable the OrbX ortho in custom scenery and see if that gives a performance boost - though you will likely get an error message the sim should still run. This isn't really an OrbX issue so much as a hardware/Xplane performance issue though additional eye candy and ortho OrbX offer could well have an impact on lower end GPU's If the numbers aren't that different then it may be a VRAM limitation but I note you already have textures turned down somewhat. You can report back with the numbers or just take a legible screenshot and post. If the GPU number is significantly higher than the CPU number then it is the bottleneck and vice versa is also true, Then when you take a flight it will show not only your fps but also the time taken to render each frame by the CPU and GPU (obviously higher is worse). You can find out if your GPU is the bottleneck by going into Xplane settings, DataOutput, and then checking the frame rate/.show in cockpit box (top left corner of checkbox options) (Sorry if the advice is already out there but after a while browsing other people's comments on one thread after another tends to start blurring the brain!). Maybe someone could suggest the best 'bang for bucks' here - most fps increase for least 'destruction' of visual delights? I need to achieve a minimum of 20fps I'd say? Disappointing to such poor fps - it was much better in the same areas with Ortho4XP, so I suppose the autogen must be to blame? But until I replace it (would a new card, say with 8GB of VRAM, really help? I don't want to spend £££100s and find no change!) what can I best adjust? To my surprise reducing the AA makes little or no difference - and it's not as if I have all the sliders pushed up to the right. My GTX970 4GB GPU may be the bottleneck - GPU-Z is showing 3800MB of memory used at EGBB, and this card is known to throttle back after 3500MB usage. But at or near airports my fps, which I have maxed at 30fps via nVidia Inspector vert sync settings (much smoother result in XP), the frame rates are usually between 12 & 18 fps. It looks pretty nice on the whole and at height all is well. I bought and installed all three parts of TEGB a few days ago (mostly because I was fed up of the colour mismatches I had in many places with Ortho4XP, and because of the autogen that comes with the ORBX packages). I have certainly read a lot of comments the past few days. Fix: Crash when typing multiple whitespace characters in a row, e.g.Couldn't make up my mind whether to add to one of the many threads already here or start my own.New feature: Identify which plugin created a dataref.New feature: Datarefs are now discovered via X-Plane's new APIs.A big refactoring of some internal code was necessary to support these changes.This is in the "Owner" field (see image below). In X-Plane 12.04 and later, we can now detect which plugin has created a dataref and is providing the value.All datarefs, regardless of plugin, should now be found when using X-Plane 12.04+ X-Plane has a new way of helping DRT discover datarefs (but not commands).The X-Plane 12 version requires X-Plane 12.04. DRT now comes with separate versions for X-Plane 11 and 12.X-Plane 12.04 includes new APIs for discovering datarefs this release uses those to more efficiently discover datarefs. More robust discovery of datarefs in X-Plane 12 discover which plugin 'owns' a dataref.
