DEMUL Ignore ATI Crimson settings #451

xbrunox76 commented 6 years ago

I apologize immediately for my poor English.

I use the demul on a pc connected to a cabinet with a 15 khz monitor. consequently my video card is a ATI in particular HD5770 1Gb of ram and I use the CRT emudriver of calamity with the addition of the crimson options that allow overboost, antialias and vsync. These options work perfectly with other emulators like supermodel, the demul instead, any change options (antialias or vsync or texture optimization), ignore them. This affects a lot the emulator performances, often when there are lansflare in the emulation as in kart club there are some strong slowdowns, or often with the vsync in demul options enabled I have slowdowns even in phases where there are not many polygons on screen (mslug6 for example or kings of the route or wwf or hokuto no ken). unfortunately I can not use an INVIDIA card as it is not possible to go out at 15khz.

I use last DEMUL and last gpudx11 plugin, and if I change tweaks options nothing in emulation change.

are there any solutions?

1) yes, for most of DirectX 11 games or applications driver settings like antialias, aniso, etc doesn't have effect. its by design.

2) club kart - there is high system load in some scenes like mentioned, but your GPU is about or below minimum system requirements. quite powerful modern PC required to run Club Kart smooth.

3) other slowdowns, especially in 2D games - it might be caused by GPU power management, if driver mistakenly lowering GPU clocks during Demul run. run some GPU monitoring tool like GPU-Z and make sure GPU clock is at max "3D" numbers then Demul running these games, and not lowering.

mslug6 - this game actually makes huge system load, since everything drawn as many thousands of little sprites, and in fact this makes quite many polygons and especially draw calls.
