Abstract: A system, method, and computer program product are provided for shading primitive fragments. A target buffer may be recast when shaded samples that are covered by a primitive fragment are generated at a first shading rate using a first sampling mode, the shaded samples are stored in the target buffer that is associated with the first sampling mode and the first shading rate, a second sampling mode is determined, and the target buffer is associated with the second sampling mode. A sampling mode and/or shading rate may be changed for a primitive. A primitive fragment that is associated with a first sampling mode and a first shading rate is received and a second sampling mode is determined for the primitive fragment. Shaded samples corresponding to the primitive fragment are generated, at a second shading rate, using the second sampling mode and the shaded samples are stored in a target buffer.

Abstract: Apparatuses, systems, and techniques for caching of compiled shader programs in a cloud computing environment. An initial request for a compiled shader program for an application executed by a first client device is received. The initial request includes a first shader key generated based on first state data. If the compiled shader program is determined, based on the first shader key, to not be stored using a shader cache, the compiled shader program is received from the first client device and stored with the first shader key using the shader cache. A subsequent request for the compiled shader program is received for the application running at a second client device. The subsequent request includes a second shader key generated based on second state data. If the second shader key is determined to match the first shader key, the compiled shader program is transmitted to the second client device.
