* All of the symptoms are exclusive to full-screen video mode with VSync enabled, and occur in all games (not specific to one particular game or mapper). I can describe the symptoms more accurately now, however: Compare the latest release of Nestopia against the latest release of Nintendulator and you can definitely tell that Nintendulator is way more responsive. The only thing I have been able to figure out with certainty is that Nintendulator does NOT have this problem, while Nestopia clearly does. I have also been unable to clearly track down a specific version of Nestopia that introduced the problem. To date, I have been unable to clearly and truly identify the problem, although I have tried many different things. ![]() Ignore all my previous claims at identifying the problem. If Nintendulator and UberNes can both be responsive even with VSync enabled, then Nestopia should be able to be responsive too. * UberNes - game is perfectly responsive with VSync enabled * Nintendulator - game is perfectly responsive with * VirtualNES - same problem (lag) with VSync enabled * FCEUltra - same problem (leg) with VSync enabled I have also tried this same repro (on the same hardware) on numerous other NES emulators (FCEUltra, VirtualNES, UberNes, Nintendulator) to compare the results: On both machines, I am using a Mayflash Super DualBox USB adaptor (for plugging two PlayStation 2 Dual-Shock controllers into my PC) as my input device. Both machines have the latest motherboard chipset drivers, ATI graphics drivers, and sound drivers installed. Both machines are using SoundMAX integrated audio chipsets. Both machines are Intel Core 2 Duo systems with ATI Radeon graphics cards (Radeon Series X1900 and Mobility Radeon X2300). This problem repros identically for me on both Windows XP Professional SP2 32-bit and Windows Vista Ultimate 32-bit. ![]() I am using Nestopia version 1.37 for Windows. If you press the "jump" (A) button, for example, to make Mario jump, there is a very long lag/delay (500ms or longer) before he finally jumps. Resume playing: note that while the horizontal shearing problem is now gone (as expected), the game is no longer responsive to controller button presses, making the game unplayable. ![]() Go into Nestopia settings, and enable VSync.Ħ. Start playing: note that the game is very responsive to controller button presses, but there are bad horizontal shearing lines everywhere due to lack of VSync.ĥ. Load Super Mario Brothers 1 (NTSC NES ROM).Ĥ.
