[Grammar] Can you correct grammar in this sentence, please.

[blablaalb]

For displacement maps we use 32 bit depth images in order to avoid render artifacts which may/might occur if we used/have used lower bit depth instead.

I have doubts whether I should use may or might and past simple or present perfect in this sentence.

I would use might/used. I would also use 32-bit.

I would use might/used. I would also use 32-bit.

Thanks for the answer. I have one question left: would it be correct to use present simple instead of past simple
For displacement maps we use 32 bit depth images in order to avoid render artifacts which mightoccur if we use lower bit depth instead.
If so, then what's the difference in using past simple used and present simple use? Would the meaning be changed?

When you say if we used you are talking about a hypothetical situation because you don't use them.
