6/1/2023 0 Comments Does vsynch help with dsyncThis also gives you the freedom to expand the number of such buffer regions you have if rendering is consistently delayed. If its not synchronized, it can cause screen tearing, an effect that causes the image to look glitched or duplicated horizontally. VSync works on most monitors and displays, so long as you have a graphics card that supports the feature, but at this point, it's something that all modern discrete GPUs should support out of the. Vertical Synchronization (VSync), helps create stability by synchronizing the image frame rate of your game or application with your display monitor refresh rate. A common thing people say is that enabling v-sync (on a 60Hz monitor) can stop the coil whine. Ive built a very quiet PC and would hate to hear any coil whine while gaming or rendering videos. If the game has no FPS limiter then next best thing is the FPS limiter built into the Nvidia driver. Enabling and Disabling Vertical Synchronization. Im thinking about buying an EVGA 780 TI Classified but Im concerned regarding various posts talking about coil whine. Then when it comes time to try to write to that buffer region again, check the fence sync and wait until its available. Vsync enabled but with an in game FPS limiter keeping the FPS below the vsync limit to avoid vsync induced input lag, so at 144Hz vsync on set FPS to 140. Set a fence sync object after you have issued the rendering commands that will use data from the buffer region you wrote to. If you are streaming data into buffer objects via persistent mapping (which should be preferred over older "unsychronized" shenanigans), then you need to perform the synchronization yourself. Desync issues in gaming will not be resolved any time in the future as it will require total restructuring of the way clients (your pc) and servers communicate. This is not about ensuring that anything has actually completed on the GPU relative to CPU execution. The point of vsync is to ensure that the new image doesn't get swapped in until the vertical synchronization period, to avoid visual tearing of the image, where half of the display comes from the old and half from the new. The bottleneck is still there, it just was. Everything is perfect, no desync, perfect timing, with all the scripts. ![]() Even though both the production of that image and its display are GPU processes (or at least, not necessarily synchronous with your CPU thread/process). V-Sync's purpose is to limit the graphics display output rate of a very powerful GPU to be in sync with your monitors refresh rate capabilities. That would basically impose a full GPU/CPU synchronization simply because someone wants to display a new image. No that would be terrible for performance. GlDrawElements glBufferData glSubBufferData glUnmapBuffer are guaranteed to be completed after swap buffer is performed (i.e.
