Game/App Problem: Microsoft Flight Simulator 2024
Error Type: Framedrop
Video Editor: None
Description: Hi, I recently have issues with Live streaming via DX12 game where the FPS suddenly drops when the stream is started which is unusual. Upon further investigation I realised the Hardware Acceleration option is disabled, and when enabled only NVIDIA CUDA is available under the hardware acceleration option. During my first installation, I remember seeing the NVIDIA NVENC H264, and NVIDIA NVENC HEVC and I selected the HEVC as my hardware acceleration. But since I updated the Nvidia driver, now I could not see the NVENC option anymore.
Assistance is appreciated, I can barely do any recording or streaming anymore.
