[Regression] Frostbite games - No longer goes ingame with Force CPU Blit Emulation (#14934)

[Ordinary205]

Quick summary

Ever since this PR #14934 got merged into master, this causes a regression on frostbite games to instantly crash before going menus/ingame when enabling WCB+RCB+RSX Tiled memory and Force CPU Blit Emulation. This crash doesnt happen without enabling Force CPU Blit Emulation.

Other details

I've noticed that enabling Force CPU Blit Emulation fixes yellow graphics with RSX tiled memory for frostbite games. Although this causes the mountain textures to render less accurately on NFS Rivals, or maybe its because "Disable MLAA" patch didnt have this issue.

Try with #14964

I don't get any reasonable crash with rivals just nonsensical errors. Since I cannot see what I'm clicking on, it makes it harder to tell if I clicked the wrong thing or not. That bug is tracked by #14682

As far as this ticket goes, I'm going to just park it until after the GPU blit issues are all resolved. It's not a good use of time to debug options meant for developers when the features around them are incomplete.

Also note that CPU blit behavior will be completely different now. RSX tiling was not implemented on the CPU blit path previously, so you will now see more issues with it enabled as it gets more features added. If you were getting better visuals this was the reason, RSX tiling simply did not work before so the yellow stuff vanished. That in itself was a bug.
