I am having issues with Battlefield 2 as well. I have narrowed it down to a WINE error, so far no one is answering my calls on this one. Please bare with me.
BF2 was working before something changed this year, it was not BF2, since the game is so old my CD is grown some moss on it. Before anyone asks, yes I have reinstalled the game but preserved my old version because I like to mod this game. Modding it was allowed by the developer as it came with a mods folder. The mods are not the issue and the game hasn't been altered in the fresh install in any way.
I tried WineHQ 6.0.1 stable and I get "0228:err:vulkan:wine_vk_init Failed to load libvulkan.so.1." the problem with that is; I never installed Vulkan, don't run Vulkan, and my Nvidia card is pretty old GT 700 series. I tried rolling back the driver. I tried Winetricks since the game uses d3dx9_24.dll but all the time I had this game, it never gave me any issue until sometime this year. I am on the verge of shelfing the game along with my other relics of the past.
I decided to check here, I know POL uses multiple versions on WINE with a Python UI, thought maybe someone here could shed some light on what is going on with BF2. I am not keen on the idea of running another install of WINE version on my system for just one game. I know I might not get an answer here, since I am not running the POL system. I figure at least I would spread the word on what is stopping my BF2 game from working.
I was already given all the snarky answers on other forums, such as buy a new graphics card, and you should try Windows 11. Let's be gentlemen and be civil to each other.
Thank you, I will check back next weekend.
