Hello, I'm getting some slowdowns in MGS3's opening cutscene and would like to find out what exactly is the limiting factor here.
Slowdown always happens at the same 3 scenes for about 2 seconds and outside of those 3 scenes the opening cutscenes do run at full speed.
Increasing EE Cyclerate seems to do nothing and going by the OSD details, at least to me it doesn't look like a EE limited scenario anyway.
Lowering Internal Resolution to 2x resolves the issue completely, while increasing it to 4x makes the slowdown worse (down to ~45 fps, instead of ~54fps on 3x Res). Looking at usage in task manager, my CPU and GPU seem to experience only light load. Increasing core clock on the GPU seems to do nothing, while giving +1000Mhz to the memory clock seems to improve the issue slightly. Though that could just be confirmation bias on my end.
So if I had to make a guess, I'd say that I'm limited by memory speed or bandwidth on the GPU. But I'm all ears for other ideas
CPU Ryzen 5800X
GPU GTX 1060 6GB
Renderer is set to Vulkan, settings which differ from stock are:
Anti-Blur - Off
VSync - On
Internal Resolution - 3x Native
Anisotropic Filtering - 16x
Blending Accuracy - High
60 fps patch - enabled
I'll attach some screenshots with OSD enabled.
