Hello. I’m developing a game that runs on Windows using Direct2D.
After recently upgrading my laptop, I noticed that the performance of the game is very poor.
After investigation, it occurs on RTX 4070 Laptop GPU, RTX 4090 Laptop GPU, and RTX 4070 Ti Desktop GPU, and there were no performance issues on RTX 30, 20, Intel iGPU, and AMD iGPU/dGPU.
The max framerate is just fine, but the low 1% drops drastically. A stall (x ms) occurs during the execution of Direct2D’s API (DrawTextLayout, DrawImage, etc.), which seriously adversely affects the low 1% frame.
Regardless of Vertical Sync or NVIDIA Reflex, performance drops significantly.
Since June of this year until now, even though I updated the driver steadily, it did not improve at all, so I made an inquiry.
