DS_grid collisions and delta timing regarding physics

[Zerb Games]

Hey guys, so I just delve into some optimization with my project that uses Box2D and right away my immediate solution was to turn all my wall objects into a ds_grid. As I've noticed drastic improvements with this system in terms of ease of use and better overall control. I'm have big issues with this however and I was wondering if there was a way to create vertexes for a larger physics object using a ds_grid, because I don't really see a way of having physics objects interact with it in any other way.

Another issue I've been having is delta timing with the physics, it's a pretty daunting issue because how inconsistent and weird it seems to be.

TT;DR Too Tired; didn't read. Shouldn't be posting this late and should go to bed. I'm just now posting this cause it's the end of my day.

Okay, so you should use objects on the create event of the room, adding them into the ds_grid first, and then use them to define the area you want as the physics fixture by "merging" them to create a series of consistent large areas (have each instance check around it, then expand it's xscale/yscale to fill the area, deleting the other instance in the process). Once you have expanded the wall instances, use their bbox positions to create box fixtures. You can see an example of what I mean by "merging" the instances from the screenshots of this marketplace asset:

This will work fine and is something I recently used in this exact same scenario for a Jam game I was working on.

Thanks, I'll be sure to try something like this when I get home.
