SORRY FOR MY TERRIBLE ENGLISH

Hello everyone,

Direct3D (DX8) have a hardware usage limit? game using maximum %30~ GPU(3D) and %10~ CPU.

I have 1080Ti and i7 8700K but game running 15- fps under 'heavy' operations(actually i think not heavy operations because game using DX8) , running idle 60 fps capped.

What i can do for game running stable 60 fps?

I see a header file(statemanager.h) in source(this file written by nvidia corp. - nvlink);

Idle usages (60 fps capped);

‘high’ (load?) usages (game running 7~5 fps)

Thread summary : My game doesn't use hardware as needed, what i can?

NOTE : Game writed with c++, 32 bit - (MMORPG).

Just a wild guess, but a game written in DirectX8 will probably not make much use of multithreading, or does it? If not, I assume you have a PC with 8 threads? If so, the ~12% CPU-usage would mean your game is CPU-locked on one thread, meaning the GPU might be just idling for >⅔rds of the time waiting for the CPU to issue it some work.
