Unity SDL tearing while flipping

Recommended Posts

MatrixCubed    199
Hey all, I've been digging around for the answer to a problem with my SDL code. The issue is that tearing occurs when moving sprites and GUI objects around the screen. I've ensured double-buffered video-memory page-flipping was implemented in the rendering code, and I've also tried to forced vsync in my video drivers (though I suspect this is only done for 3d rendered games). This occurs while fullscreen. I've got an nVidia GeforceFX 5200, and the latest (71.84) Detonator drivers. It's not really high priority on my list of things to work on for my game engine, but I thought I would bend the community's ear, in case there is a known workaround for this unsightly artifact. Thanks for your time! :)

This very thing is what made me give up SDL. I never found a way to fix it. It doesn't seem to be a problem when using OpenGL with SDL, but only with the "built-in" 2D support.

edit -- Just to clarify, I was using SDL under Windows. This may not be an issue under linux/mac.

      I'm looking to form a new game development team, mostly for training purposes.
      About me:
      I'm a student - Unity C# developer, who worked part-time in this industry for a couple of years already. I've been a lead developer in many "random collab groups" as well as a few companies. I specialize in creating 2D games for Android, but I'm looking forward to trying out new things - especially 3D development.
      Currently, I've got one Android game close to a release so I'd work for this team in my spare time. 
      About the project:
      I've been thinking about creating a simple tycoon-like simulation game for Android (and PC eventually), inspired by the Game Dev Story (initially released by Kairosoft in 1997) https://en.wikipedia.org/wiki/Game_Dev_Story 
      I haven't done much planning though, therefore I'm looking forward to hearing out your ideas.
      Right now, I've only created a test 3D scene using placeholder models and implemented a simple pathfinding system for me to play around with:

      https://i.imgur.com/nHZerOT.png
      I'm looking to work with people who are:
      - willing to take a position of a: 3D modeller/2D artist/Designer
      - not necessarily very experienced, but eager to learn and improve their skills
      - active - check in at least once a day
      If you'd like to apply for a different position which I didn't list here, you are welcome to contact me as well.
      While this project is created mostly for learning purposes, if we ever get to release it and generate any revenue - you will recieve a certain percentage of it.
       
      To Apply:
      Send an email to rk.softwaredev@gmail.com
      Introduce yourself and attach an example of your work (if you have any)

      Hello.

      We're a two-member team and I'd like to introduce you our game - Feudal Alloy. 
      It's a metroidvania-style action RPG with fishbowl-powered medieval robots.

      We've been working on the project for a few months. I'd be happy for any feedback.
