Trouble using Direct-to-Rift in DirectX 9 with 0.4.3 SDK

Thanks virror, I figured since 4.6 beta 18 was kind of old that Unity 4.5.5 might work for me and it did, but I still get the same direct-to-rift DirectX9 problems. Although I'm not sure if it's a big deal anymore because I noticed that my DirectX9 performance is also very poor with the new 0.4.3 Oculus Rift Unity integration, but Directx9 support would be great just for compatibility with older video cards so I haven't given up on getting it to work yet. I attached a Tuscany scene build I made in Unity 4.5.5 with directx9 support, I can get it to work in extended mode but not in direct HMD access mode, it just gives me a blank screen. If anybody has a minute and could test this build in direct access direct-to-rift mode and see if it shows up or not I'd appreciate that. Please don't try to test it with the -force-d3d11 switch, I want to know if the DirectX9 is working for you. Thanks
