I know there are plans of removing 32bit optix builds. I understand the extra work in maintenance and testing that is caused by keeping both 32bit and 64bit.
Our one reason for using 32bit optix, is for the, IMHO, flagship feature of Visual Studio, edit and continue. For some reason, they have yet to add in support for edit and continue in native 64 bit c++ builds.
For graphics programming, edit and continue is nothing short of amazing. I can break, edit code, continue, and immediately see changes.
I’m also of course a fan of using statics, break, edit the static in the debugger and continue. These give you a “poor mans” edit and continue.
I’m hoping Microsoft does something to update edit and continue. It is the only reason we internally keep a 32 bit build ourselves.
