EDIT 2017-05-14 dvb. Concern nonetheless energetic to this very day, see geforce discussion board hyperlink in primary query.
Word 3: “Stoltverd” has posted a “repair information” on geforce discussion board. It has workarounds for non-OpenGL video games.
Word 4: My workaround for OpenGL video games: use HDMI output to exterior monitor. (In my case, the one recreation I care about is my very own, and I take advantage of an enormous low-cost HDMI TV for demo.)
EDIT 2016-03-06.
Word 1: Apparently this can be a recognized situation with Nvidia.
When you’ve discovered right here attributable to similar downside, please stoke the collective “please repair it” by submitting a “query” at https://nvidia.custhelp.com/app/ask.
Word 2: Does not occur on exterior monitor. Additionally does not occur on inner show if exterior monitor is mirroring. (Shock.)
I am creating my recreation immediately in C++, OpenGL, and SDL2.
On an Alienware 15 R2 laptop computer with Nvidia GTX 965M, I get display screen tearing in a curious diagonal line like proven beneath. It goes throughout the window prime left to backside proper.
The picture beneath is taken throughout a display screen fade-in, so exhibits only a brightness line. However it occurs between any two totally different frames.
If my window is full display screen, the road goes top-left to bottom-right of the entire display screen.
Similar code runs tremendous (no tearing) on: All macs, similar laptop computer on Intel built-in GPU, desktop PC with Nvidia 730.
Similar laptop computer seems tremendous with different video games, Chrome+Shadertoy, &c.
Important loop seems one thing like:
// setup code
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
SDL_GL_SetSwapInterval(1);
flags = SDL_WINDOW_OPENGL;
SDL_CreateWindow(... ,flags);
// primary loop
whereas(1) {
this->checkEvents();
SDL_GL_SwapWindow(this->mainWindow);
this->doGlDrawing();
}
Grepping boards, I’ve seen experiences of some OpenGL video games exhibiting this on Alienware & different Dell laptops.
All options welcome! Thanks.
