            Bug ID: 56427
           Summary: Regression on Battlefield 2 in the new wow64 mode
           Product: Wine
           Version: 9.3
          Hardware: aarch64
                OS: Linux
            Status: UNCONFIRMED

          Priority: P2

Enabled game HUD

Hardware: MacBook Pro 14 (M1 Pro cpu)
OS: Ubuntu 22.04 ARM64 on virtual machine (VMWare Fusion)
Game: Battlefield 2 (32Bit, DirectX 9) on Wine 9.0 WOW64

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

I noticed that if turn off the HUD in the game I get over 200-300FPS on low
settings and >100FPS on max settings, and the game starts working very
smoothly. 

I do same on x86 Windows PC and enabling/disabling HUD does not affect FPS
(maybe 1-3fps more)

I also did a few tests on an Intel PC with wine 9.0 (WOW64), which show the
same problem

Galium Hud:
 Enabled game HUD: 
  Draw Calls: ~250
  Frametime, ms: ~40ms

 Disabled game HUD
  Draw Calls: ~230 
  Frametime, ms: ~4ms (10x less)


Question: It is possible to somehow debug\profile why this is happening? It's
just HUD, why does it need so many resources. 


here is video how it's looks like

Steps to repeat:

1. download demo -> https://www.moddb.com/downloads/battlefield-2-updated-demo
2. install dx9 dlls over winetricks
3. enable\disable hud over console, press ~ in game
   -- Enable `renderer.drawHud 1`
   -- Disable `renderer.drawHud 0`
   -- Show in game FPS counter `renderer.drawFps 1`

   -- Disable frame rate limit `game.lockFps 0`
