#Difference between directx9 and 11 code

While a lot of people that play this game would be tech savvy enough to click on the best choice for their system, I felt like there are a lot of users that just want to click on the game icon and get the best experience automatically for their system. I think this promotes good programming practices, sets up for easier porting to other platforms, and makes my game engine easily reusable in the situation where it actually uses more than 2G or 3G of RAM. To compound the multiple exe problem, throughout development I've also compiled 32-bit and 64-bit versions of the game. The vertex and pixel shaders are also different between shader model 2 and shader model 4. All the data is precompiled for fast loading, and DirectX 9 uses some repeated data and index buffer tricks to implement fast instancing. Both versions have their own copies of all the game data as well. There was a DirectX 9 executable, and a DirectX 11 executable.

#Difference between directx9 and 11 code

It got the code ready for supporting multiple platforms, but for a distribution across windows PCs, it's not ideal. I treated it as a separate platform - as if I was implementing a port to another OS. The bad part of this, is that the way I originally wrote the code was to have a fully different version of the game. The takeaway there was that DirectX 11 performed much better on newer systems and it was worth having two versions of the game - though at this point I'm curious how many DirectX 9 only users are out there. After some refactoring I now have 1 of each.ДЄ while back I did some testing on DirectX 11 vs Directx 9. TL DR? For some reason I had 4 game executables and 2 sets of data. This contains a lot of technical programmer nonsense.
