Hi Chris,

My recommendation would be to grab a newer version of the VMD source (like a58). A55 is from October of 2021, which predates by about a year the release of CUDA 12 that drops support for texture memory. If you really want a55 for some reason, you'd need to compile with cuda 11.8 which had those texture memory features deprecated but not dropped.
