Weird loading screen and low frames

Postby inventorJS » Sun May 05, 2019 9:26 am

I have had FlightGear for a while now and have loved the program until I built my new pc which runs any game fine with high framerate. I launched FlightGear for the first time and found that everything ran fine but got some weird lag and frame drops when I looked around the cockpit very quickly. I used to play on a MacBook air and it ran fine despite it having far worse hardware. I quit the game and left it for a while and then booted it up another day. Once I started the game, the loading screen came up and I was met with this:

I would really like an explanation as to why this is happening.
I am running windows 10 pro with an AMD ryzen 5 2600 without overclocking and have an AMD Radeon RX 570 4GB.
Any help?

Are you sure it's using the dedicated RX GPU and not any integrated GPU if you have one? That actually looks like bad drivers :? Try updating them as well.

FlightGear genally doesn't play by the rules, unlike those games. FG has a pretty ancient codebase, so it can't take advantage of multiple threads. Modern CPUs aren't getting better single core performance either. If the aicraft you are using is complex enough, stutters are expected as textures load from disk. You could try enabling the DDS texture cache in the rendering options if it's available in your FG version, or moving FG to an SSD if you have one available.

The main problem here I think is drivers. If something isn't working right then as indicated by the wierd splash screen that will cause very bad performance.

I have updated my drivers and unfortunately, nothing has helped :cry:. I am not sure where to go to at this point.

I have just found out that if I select a different aircraft such as the UFO, i don't have any issues

This is not first case, when extremly powerfull CPU/GPU runs this sim in low fps and CPU/GPU indicated load is very low :( Weird splash screen is always evidence of the driver related problem.

I have done a complete clean install of drivers and for some reason the issues still persist. Could it be because I have a mining card with gaming firmware on it?? I am not sure about what to do at this point. I have also sent back my graphics card and received reports of everything being fine.
