Is it my PC Hardware or Monitor causing the slow reponse time using V-Sync?

post #1 of 2
Thread Starter 
I play Left for Dead 2 online and I notice when I use V-Sync there is a considerable delay to the monitor making the game almost unplayable as my control becomes awful and delayed and I quickly get a lashing from other players. Turning V-Sync off is not a problem as I don't seem to get any screen tearing what-so-ever in this particular game. But I've started to notice it also in other games, but more so in L4D2 probably as it is the only game I play online and requires a bit more intense control down corridoors and the like.

My rig is as it appears in the sig with all the latest drivers.

My question is, I understand from reviews that the monitor I have (in the sig) is not ideal for gaming for the slow response time but I haven't really noticed it, only when turning V-Sync on. Does anyone think if I was to get a better monitor, the response time would be better with V-Sync? Or could it be that the response delay is caused by something else. Is V-Sync just known for this, paticularly in the Source engine?

Thanks in advance! thumb.gif

It's VSYNC. Triple Buffering and other things are supposed to alleviate it, but honestly I say forget about VSYNC and use one of the many programs available to simply lock the framerate. Since the engine is likely never going to drop below 60fps, just match the cap to the refresh rate and you get the benefits of VSYNC with none of the downsides. Even better is that your GPU will likely never have to be fully loaded, and will run much cooler and quieter as a result. Also, unlike VSYNC, if your framerate does drop, it simply will drop by single frames instead of multiples of 60. Oh, and no input lag.
