xwa_ddraw_d3d11's Issues

X-Wing Alliance does not launch after adding the ddraw files.

Hello, I have just installed X-Wing Alliance on Windows 7 and after updating the game and later adding the ddraw files into the game's directory, I decided to give it a test run to see if it works. I tried launching the game numerous times and it didn't show up.
I decided to check if the game was even running so I ran Task Manager and lo and behold, it's process was there, but the game itself was nowhere to be seen on my display, not even a black screen, it's not like it's even there.

(Note : I've not added any mods to this, it's a fresh installation)

I play X-Wing Alliance game on win10 problem!

Play in WIN10 FPS is too low(15fps) :(

The std::map cache must be reset each time a new ship is loaded in the Tech Room

When a new ship is loaded in the Tech Room, the hash for the new meshes may sometimes collide with the old meshes stored in _meshVerticesViews, _meshNormalsViews, _meshTextureCoordsViews, _vertexBuffers, _triangleBuffers and _vertexCounters, causing artifacts.

We just need to call FlightStart every time a new ship is loaded to reset these maps.

One way to do this is by counting the number of draw calls executed during one frame. Then, in SceneEnd() we can call FlightStart() to reset the cache if we're in the Tech Room and the number of draw calls changed since the last frame. This is an example of how I fixed this problem in my branch:

https://github.com/Prof-Butts/xwa_ddraw_d3d11/blob/d3d_hook_merge/impl11/ddraw/XwaD3dRendererHook.cpp#L191

To reproduce this problem, as soon as the game begins, load the Tech Room, then click on "Cycle Craft" 9 times or until you reach the Preybird Fighter. Then click one time on "Cycle by Type" so that the the shuttles are loaded. Then click on "Cycle Craft" 11 times or until you reach the "System Patrol Craft". This ship will display broken geometry.
