From 0b8b9614426d099be7c5a02c147c9f97631c1c2f Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Fri, 22 Jan 2021 22:17:23 -0300 Subject: buffer_cache: Add extra bytes to guest SSBOs Bind extra bytes beyond the guest API's bound range. This is due to some games like Astral Chain operating out of bounds. Binding the whole map range would be technically correct, but games have large maps that make this approach unaffordable for now. --- src/video_core/buffer_cache/buffer_cache.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'src/video_core') diff --git a/src/video_core/buffer_cache/buffer_cache.h b/src/video_core/buffer_cache/buffer_cache.h index a296036f4..2a6844ab1 100644 --- a/src/video_core/buffer_cache/buffer_cache.h +++ b/src/video_core/buffer_cache/buffer_cache.h @@ -1243,9 +1243,15 @@ typename BufferCache
