XEMU resolution scaling prevents Metal Arms from booting #1029

Bug Description

Metal arms will not initialize FMVs/main menu unless scaling is turned off or below 4x at game start.

To reproduce issue: Start game with scaling enabled Wait for game to start Continue waiting Disable scaling, game starts immediately.

Additionally, scaling causes FMVs to play at a slower rate proportionally to scaling. 2x and 3x produces same results as 1x, but anything above causes stuttering that gets worse at higher scales.

Here is a video of the issue. For posterity's sake I didn't wait, but the loading screen has appeared for upward of 10 minutes. https://youtu.be/2e-dTMTN_aU

Expected Behavior

Boot game, game loads into FMVs

Maybe a difference b/w Nvidia/AMD? I can recreate pretty reliably

I'd suggest looking at the depth buffer format used by this game to see if this is a dup of #278. There is something pathological with the AMD driver and 24s8 depth textures that causes massive amounts of time to be spent doing CPU-based conversion. I'd expect any increase in resolution to increase the amount of time spent.

You can also run a profiler to see if an unusual amount of time is spent in the driver in some other conversion function, comparing profiles at different resolutions to see if something jumps out when the scale is increased.
