  * iidx25 and above requires SSE4.2 instruction set. If your CPU is too old, you will not be able to run the game, it will crash with `EXCEPTION_ILLEGAL_INSTRUCTION`. Patches exist that may help you boot the game without some features (not covered here).
  * iidx31 and above requires AVX2 instruction set. If your CPU is too old, you will not be able to run the game, it will crash with `EXCEPTION_ILLEGAL_INSTRUCTION`. You'll need to find a way to completely disable videos to make the game run (usually a patch to disable all videos, or deleting videos in `data/movie` folder).
  * iidx31+ will most likely not run on integrated GPU (Intel or AMD), resulting in a crash when entering song select screen. This seems to be issues with drivers not properly supporting DX9.
+    * Some Iris Xe users have reported that downgrading drivers to an older version may resolve this issue (which?)
  * On some GPUs, DX9on12 may crash iidx31+. Turn off `DX9on12` / `9on12` options on these versions of iidx. Your log will be spammed with `afputils: CTexture::set_texture_image テクスチャの取得に失敗` or `W:CTexture: no such texture: id` and the game will eventually crash.
  * iidx25 and above: if the game suddenly stopped launching on Windows 11 around Feb/March 2025, you may be running into [Issue 260](https://github.com/spice2x/spice2x.github.io/issues/260) caused by Windows Update. Update to build `spice2x-25-03-03` or newer which contains a workaround. As a side effect, `REVERB EX` filter will sound different from what it's like on Windows 10. Ensure that `-audiohookdisable` is not enabled, since audio hooks must be installed for the fix to be applied.
  * If you see `EXCEPTION_INT_DIVIDE_BY_ZERO` crash during boot, try enabling `-iidxdisablecams`.
