FFX_FSR2_OPTION_UPSAMPLE_SAMPLERS_USE_DATA_HALF option is not working

Open Bonefest opened this issue 3 years ago • 2 comments

Hi, I'm trying to compile the FSR 2.1 Using UE 4.26 on Windows with the FFX_FSR2_OPTION_UPSAMPLE_SAMPLERS_USE_DATA_HALF option enabled, but it produces a compile-time shader error related to the inclusion of the ffx_fsr2_force16_begin.h file. I see that the current version doesn't have that file at all. Could you please clarify what's going on, is it just an unfinished option or maybe I've missed something?

Yes, same to you, and it seems to be the most useful optimization compiler option., so hope it works.

I also have this problem, I couldn't compile FP16 mode. It errors when FFX_HALF is also defined. Update: actually, if that include is just deleted, it will compile.
