Apex crashes after running out of memory even though it has tons

---------------------------
Apex Crash - Out of Memory
---------------------------
Apex crashed because it ran out of memory.

The most common causes of this are:

• "Texture Streaming Budget" is too high in your video settings. Lowering this can help.

• All other programs plus Apex combine to use too much memory. Quitting other programs can help.

• Your Windows page file is set too small. Increasing the page file size can help. (The page file lets Windows move less important memory to disk until it's needed again.)

TECHNICAL INFORMATION:
• Apex was using 3.7 GB of physical memory.
• Apex was using 5.7 GB of virtual memory.
• Apex failed to allocate 2.0 MB of memory.

• Your PC has 16.0 GB of memory physically installed.
• Your PC has 128.0 TB of virtual memory (with the page file).
• After Apex exited, your PC memory load is about 50%.

i have it on very low texture streaming budget but it keeps on crashing, any idea how to fix this?
