Memory management in gaming rendering

A server system, comprising:

• one or more CPUs;
• one or more GPUs;
• and
• memory storing one or more programs for execution by the one or more CPUs and/or GPUs, the one or more programs comprising instructions for:
• executing on the one or more CPUs a plurality of online gaming sessions in parallel for a gaming title;
• rendering by the one or more GPUs a plurality of image frames for each of the plurality of online gaming sessions using a first sequence of compiled shaders;
• identifying a performance criterion for the plurality of online gaming sessions associated with the gaming title;
• collecting real-time usage statistics characterizing execution of each of the online gaming sessions;
• and
• based on the real-time usage statistics, modifying a first shader in the first sequence of compiled shaders to improve performance of the first sequence of compiled shaders with respect to the performance criterion for the plurality of online gaming sessions, thereby creating a modified first sequence of compiled shaders;
• establishing a shader hash table that associates each of a plurality of performance criteria with a respective sequence of compiled shaders, including associating the performance criterion and the first sequence of compiled shaders in the shader hash table;
• and
• storing the shader hash table in a shader cache of the memory.

A non-transitory computer readable storage medium storing one or more programs configured for execution by one or more processors of a server system, the one or more programs comprising instructions for:

• executing on one or more CPUs a plurality of online gaming sessions in parallel for a gaming title;
• rendering by one or more GPUs a plurality of image frames for each of the plurality of online gaming sessions using a first sequence of compiled shaders;
• identifying a performance criterion for the plurality of online gaming sessions associated with the gaming title;
• collecting real-time usage statistics characterizing execution of each of the online gaming sessions;
• and
• based on the real-time usage statistics, modifying a first shader in the first sequence of compiled shaders to improve performance of the first sequence of compiled shaders with respect to the performance criterion for the plurality of online gaming sessions, thereby creating a modified first sequence of compiled shaders;
• establishing a shader hash table that associates each of a plurality of performance criteria with a respective sequence of compiled shaders, including associating the performance criterion and the first sequence of compiled shaders in the shader hash table;
• and
• storing the shader hash table in a shader cache of a memory.
