Simply put, I want to know if anyone has successfully run GZdoom with a resource intensive wad and if they were able to use a much lower end graphics card and CPU to do so. Playing regular Doom, Doom2, and the Final Doom IWADS with Gzdoom, Riva TNT 64 and a celeron 366mhz CPU seems possible, but even with most features turned off (dynamic lights included, used 640x480/400 res to test), there were hickups at odd points dropping below the Doom standard 35fps. My own wad project, which is very intensive, will run on a celeron 366mhz in software mode, at a constant 35fps, no FPS slowdowns using 320x200 (not even gothic99 runs without hickups on this machine in software mode at 320x200). However, my project using GZdoom on the specs I just listed produced unplayable results.
Obviously anyone who has a super beefy machine are proud of getting ridiculously high FPS thanks to the FPS cap being removed long ago in Zdoom 2.x ports... not to mention that they would have no issue running my current project at 1280x1024 res with all features turned on if their machine can run games like Doom3 or HL2 without performance issues. "cl_capfps 1" is the console command to use if you intend on testing things out after reading this post.
Also, does GZdoom rely on more modern features such as Transform and Lighting or any other form of geometry assisting?
