Prepar3d Performance Loss

Featured Replies

Hello, I reinstalled P3D the other week and I was averaging about 30fps in the FSLABS on low to medium settings, 40fps in the aerosoft a330 and 40fps in the QW787. For some reason suddenly the performance has dropped and now I am struggling to get 20FPS on the ground in the FSLabs, I barely use dynamic lighting and my settings haven't changed. Any ideas what could've happened? My specs are currently: AMD Ryzen 1600 AF, GT1030, 16GB 2400MHZ RAM, 1TBHDD. I have tried stuff like updating drivers and deleting the shaders file for it to regenerate but nothing has changed it, thanks.

Have you tried deleting the prepar3d.cfg file and let it build a new one?

Here is the link to system requirements -- https://www.prepar3d.com/system-requirements/

Is your GT1030 the 2 Gb version? It looks like your specs don't meet the minimum requirements.

Gigabyte x670 Aorus Elite AX MB; AMD 7800X3D CPU; Deepcool LT520 AIO Cooler; 64 Gb G.Skill Trident Z5 NEO DDR5 6000; Win11 Pro; P3D V5.4; 1 Samsung 990 2Tb NVMe SSD: 1 Crucial 4Tb MX500 SATA SSD; 1 Samsung 860 1Tb SSD; Gigabyte Aorus Extreme 1080ti 11Gb VRAM; Toshiba 43" LED TV @ 4k; Honeycomb Bravo.

 

Had a similar issue. Turned out that I had selected 4XSSAA intstead of 4XMSAA in my graphics settings...a simple error when restoring my settings. Regards.

It's the 2GB version and supports directx12 so meets minimum requirements for my V4, have got a GTX1650 super on order but it's taking forever due to COVID. I'll have a go with the CFG cheers

I deleted my P3D CFG and reset some other stuff at the same time and I'm still getting the lower fps, this started to happen just the other day whilst I was messing around with my addons cfgs, any chance this could have anything to do with it?

Yeah I was using the project fly addon editor to add some scenery and project fly crashed messing up my addons.cfg so I thought I fixed it but not well enough

I deleted both of my addons.cfg, the one in program data and the one in appdata and that hasn’t fixed it

Not sure if this is at all related, this started when it didn’t let me register SODE in the SODE menu when I reinstalled SODE and it still doesn’t, I had to make a custom entry, anyone have any ideas if this could be linked?

Try disabling SODE and see if the performance comes back.  If it does then we will know the culprit.

Thanks everyone for your help, at the moment my PC is extremely bottlenecked as I have a decent CPU but am still waiting for my GPU to come so at the moment it is fragile and small changes can massively change performance but I've messed around with some settings and managed to get back to 30FPS with the sim still looking decent, thanks.

In the last few times I've installed P3D, I always find overtime as more scenery and aircraft are installed, the performance slowly drops, as I am running it on a HDD, is there any chance this could be fixed by installing on an SSD?

you will  definitely get a performance increase with an ssd but its the loading time that's the big benefit , its time to ditch the HDD my friend, just about all devs / programmers for p3d highly recommend ssd's . 

my drive specs:

500GB nvme for OS W10

2 TB Nmve for p3D v5.1 HF1

x3 500gb SSD's for addon scenery that's not too fussy where it lives 

1TB SDHDD for downloads

this drive set up is not unusual these days 

cheers

Thanks, if I was to get a 500GB ssd, would it be fine keeping all of my addon scenery for now still on the HDD? Like cause I have a lot and don’t want to pay too much for multiple ssds.
