Chasm has gone 64-bit! Well, truth be told, the Mac and Linux builds have long been 64-bit, while the Windows version remained 32. However, Steam has recently announced that they are phasing out 32-bit Windows support, and after feeling the memory limitations of 32-bit in my development environment, I decided it's finally time to embrace the future as well and go fully 64-bit.

Thanks to the modernization work that's been done over the past couple years (including the FNA transition and SDL 3 upgrade), Chasm should be running comfortably on modern systems for years to come. Apologies again to anyone that's been affected by the recent growing pains, and please let me know if you run into any issues.
