Performance debug

[Moxnatiy]

Hardware: MacBook Pro 14 (M1 Pro cpu)
OS: Ubuntu ARM64 on virtual machine (VMWare Player)
Game: Battlefield 2 (32Bit) on Wine 9.0

Problem: Low FPS, around 20-50fps on low settings

I noticed that if turn off the HUD in the game I get over 200FPS on low settings and >100FPS on max settings, and the game starts working very smoothly. I do same on Windows VM and x86 Windows PC and enabling/disabling HUD does not affect FPS

Windows 11 ARM with native emu shows around 50-80Fps, thanks for box64 you did a great job 🥹

Question: It is possible to somehow debug\profile why this is happening?

here is video how it's looks like:

Hi

Nice ticket.
So, you are running a 32bits games using new Wow64 on wine I guess? If that game use OpenGL (or WineD3D) the slowdowns are probably becasue of the new Wow64 support: openGL can be slow on 32bits apps as some buffers needs to be copied in lower memory space.

Unless there is simply some opcode missing in the Dynarec when the HUD is shown. Use BOX64_DYNAREC_MISSING=1 to have some printout of the missing opcode (note that there might be some miising opcode on some wine fnction, it's notmal, it's some AVX and friend opcode that are not executed anyway).

Yes you right, new WOW64 mode, game use DX9 -> WineD3D (OpenGL)

I'll just retested on Ubuntu (Intel PC) with same wine in WOW64 and unfortunately, get the same behavior BUT I'll try to install a DXVK over winetricks and it's fixed performance issue I get over 100fps with HUD. and unfortunately VMWare VM not provide any acceleration for Vulkan :(

Anyway, Looks like it's a WineD3D (OpenGL) issue

here is missing opcodes when I try run with BOX64_DYNAREC_MISSING=1
