Nik_TB Posted October 19, 2020 Share Posted October 19, 2020 Hi It is a bit disappointing to have such reviews and as a result purchased Orbx Southern UK with Southampton Airport - loaded OK but on running XP11.5 OpenGl and Vulkan. I had been happily running at 35-40fps and now its dropped to 14!! For the life of me I cannot understand why... can you help please? I'm sure there is a fix simwhere...

Jon Clarke Posted October 19, 2020 Share Posted October 19, 2020 Welcome to the forums. TEGB South is very demanding especially in the London area. I doubt you are getting 14fps everywhere in TEGB South so please expand and let me know where these framerates are happening. In order to assist more I need your PC specs and also your XP settings and whether you are using Vulkan or just OpenGL in 11.50. Thanks Also please attach your scenery_packs.ini as an attachment and not a pic of it please. Link to comment Share on other sites More sharing options...
D Erickson Posted October 20, 2020 Share Posted October 20, 2020 I have the same problem. Just installed TEGB South. Flew out of Duxford flying south a bit and then SE towards the coast with a frame rate in the 40+ region and it began steadily falling by the time I'd hit Brookman's Park. At Damyns Hall and the Dartford Crossing it had dropped to 3 (must have been that beautifully-rendered bridge). I can send you the log.txt and scenery_packs.ini, if you think it's useful. I'm running on a Mac and have no problems with the Washington State SD scenery. Runs beautifully at around 40-60 fps with the default settings for my device.

Jon Clarke Posted October 20, 2020 Share Posted October 20, 2020 Welcome to the forums. Please send me the XO log and your scenery_packs.ini plus tell me your PC specs, XP settings and if you are only seeing the fps drop around the London area. By London area I am talking about the area that is within 30 miles of London City. As a test, what fps are you seeing at KLAX which is another high resource demanding area both with TE SoCal or just default scenery. Link to comment Share on other sites More sharing options...
Nik_TB Posted October 26, 2020 Author Share Posted October 26, 2020 Hi As requested the attached files. My System is as follows x64 base - Window 10 Home Intel i7 3770 3.4 (turbo 4.0) P8Z77 thunderbolt 16GB Mem Graphics: GTX1070 X Plane 11.50r3 OpenGL and Vulkan Plugins> DataRefTool, ASXPC connect,Skunk,xJet,SAM,XPLM,XPUIPC,P Widget,Xsaitek, Navigraph Scenery> Ortho, x-Europe both excluded with xOrganiser Aircraft used: King Air 350 Airfoillabs. Ran a flight from Southampton with Orbx GB Southern and Southampton scenery East along the South Coast then up to Gatwick then west back to Southampton via MID. ILS approach breaking off at 1000 for a circuit to land. These are the recorded values from A. Straight ahead of the pilot screen and B. Down into the cockpit i.e. no scenery Three graphic scenarios.... 1. OpenGL Visual Effects, Texture and World Obj = High AntiAl = 2xSSAA+FXAA 2. OpenGL Visual Effects, Texture and World Obj = Medium AntiAl = 8x 3.

At the moment, I've moved the old preference folder out to rebuild a new Preference folder for a clean start, to see if there is anything different... will advise.

Jon Clarke Posted October 27, 2020 Share Posted October 27, 2020 I have rearranged your scenery_pack slightly so drop it in to your Custom Scenery folder to replace the existing one. Please note you have a rogue entry at the very bottom of the scenery_pack: ys/ SCENERY_PACK_DISABLED F:\Ortho4XP\ORTHO\zOrtho4XP_+50-002/ scenery_packs.ini Looking at your XP Log file indicates you have a lot of other things going on like LUA scripts etc. For example my Log file is 176 KB in size and your is 629 KB. That indicates that your are running much more resource demanding addons, scripts higher demand planes or similar. I am not sure that with all those instances runn9ng and being in a high resource demand region like TEGB South, that you have the PC specs to cope. is there a reason that you are not using Vulkan? You say in the narrative in your £ Three graphics scenarios" that they are all in OpenGL. The whole idea of Vulkan was to unleash the better fps and performance abilities that were/are stifled by OpenGL. My performance ox XP 11.50 in Open GL is a lot worse than Open GL in 11,40, hence I only use Vulkan and can fly anywhere including TEGB South with much higher fps than in 11.40. My PC specs are higher than yours but I am just talking relatively speaking. I can suggest you try using Vulkan with the same XP settings and see if there is a difference. I would use a default XP plane like the Cessna or the Cirrus for a test and also if possible disable all your LUA scripts for the test. I am concluding that you are running too many additional processes in a high demand area, that your PC specs are finding hard to deal with. This plus the fact that you are not using Vulkan as the default choice is contributing adversely to performance. It is not the result of a faulty Orbx addon I assure you. @D Erickson Some of my above comments may be relevant to you as well., and note that TEGB South is in HD vs your Washington in SD Link to comment Share on other sites More sharing options...
D Erickson Posted October 27, 2020 Share Posted October 27, 2020 Thank you Jon. This was very helpful. I have no additional scripts or add ons, like Nik_TB, but I didn't have Metal turned on and, after following the instructions at this XPlane support video to find the optimal settings (here), everything works just fine. All of my planes are purring along at about 30FPS now...In fact, I was able to *increase* my video settings with Metal enabled. Brilliant. Thanks again!

Jon Clarke Posted October 28, 2020 Share Posted October 28, 2020 Good news and sorry for going on about Vulkan when in your particular circumstance I should have been referring to Metal Link to comment Share on other sites More sharing options...
