Low frame rates

Post by doodlebug » Sun Jun 09, 2019 1:34 pm

Could all those suffering low frame rates please post their system specs in their forum signature.
We are currently investigating and this would help greatly in our efforts to fix the problem

Thank you - Osh

I have low FPS too, while all other addons runs smooth (PMDG 737NGX, 747 QOTS II, 777, TFDI 717, Maddog X, etc...)
I use P3D V4.5 with HF1, ORBX Global Base and various Airport DDONS FROM ORBX, Aerosoft, Justsim, etc...
Weather engine: Active Sky for P3D V4 / Active Sky Cloud Art.
Shaders enhanced with PTA.
AI Traffic with Ultimate Traffic Live.

Some of my addons uses TFDI's TrueGlass and TrueLight with no issues.

Milviz PC-6 Porter equipped with the Flight1 GTN 750/650 (Could use an option with only the 750 and standard COM/NAV2 radio setup)

My system specs in signatur:

AMD FX-8350 8-core, 16GB RAM, GeForce GTX970, P3Dv5.3, and the Porter crashes any scenario almost immediately upon loading. None of my other addons do this; there isn't even a frame-rate hit, it just freezes the game and CTD.

Watching on Process Explorer it drives P3D's Private Bytes over 8.5gb and Working Set north of 4.5gb with DirectX crash handlers opening immediately.

This is a snapshot of the moment before the CTD with any addon sceneries or other enhancements switched off: just the basic P3D setup with the Porter. At this point the scenario bar had just gotten to 100%, then immediate CTD thereafter. First mem column is Private Bytes, second is Working Set.

Super. Doesn't say that anywhere on the product page.

Thats because it is not sold as V5 compatible on the product page, only V4. The V5 update posted here is only an installer update and maybe an MVAMS update. P3DV5 handles memory a lot differently as it is DX12 and for some reason the VRAM requirements are steep.

If you remove the realglass and truelight it might drop the memory usage but 4GB card is still sketchy.
