Logging Offload Behavior

This topic only applies to Intel® 64 and IA-32 architectures targeting Intel® Graphics Technology.

You can enable logging of the offload process by setting the GFX_LOG_OFFLOAD environment variable to the desired logging level. For example, to enable logging, enter the following:

set GFX_LOG_OFFLOAD=2

Enabling logging significantly increases the overhead of offloading, so it is recommended to use it only for debugging.

To disable logging, set GFX_LOG_OFFLOAD to either an empty string or 0, just unset the variable altogether. For example:

set GFX_LOG_OFFLOAD=
