Is there anything that can be done about mouse fps drops caused by mouse movement in games like Evil Genius?

Enabling Cursor Hook in dgV does not help?

It causes a crash 🙁

It looks like if dgvoodoo isn't doing the scalin, stretching the problem does not happen

The Evil Genius is like a name implies, the biggest enemy of dgVoodoo 😁. The game actually works better without dgVoodoo 🙁 The problem is, I wanted to render the game at higher resolution and upgrade swapchain and dgVoodoo always was the best tool. Yet this game refuses to cooperate

I tried the GOG version of this game but I didn't have problems with the fps and the cursor (through dgVoodoo) in the first place.
I thought it is the usual problem with flashing double cursor coming from the hw cursor emulation but I'm not sure if this game uses a hw cursor. Is there any option to switch between hw/sw?

(enabling cursor hooking also didn't casue crash)

Hey, thank you so much Dege for answering and testing the game.

I am forcing the game to a higher resolution. Doesn't really matter what, I tried 1920x1440 for 4/3 aspect or 2560x1440 for 16/9 aspect ratio. When I do that, the game seems to work fine at first, but when I move my mouse, frame drops occur. Even worse is when I keep the left mouse button pressed down - FPS drops to 10-15.

EDIT: Well, I started digging after your question - there is an option to change cursor. It's in DynamicResources\Config\concept.cfg

There are two options:
Mouse exclusive=false
ForceSpriteCursor=true

If I turn off ForceSpriteCursor and enable Mouse exclusive it seems that I don't have FPS drops anymore. The cursor option in dgVoodoo still causes a crash though, unless I don't force resolution.

And disabling that option is undesirable as it makes the mouse super fast, at least on my system 🙁

I use an AMD RX6590 XT GPU and I am on Windows 10 22H2 so I guess my system is not ideal
