I wonder if someone can assist me here. I have a computer system comprised of an AM2+ motherboard, Phenom II CPU, DDR2 memory and Windows 10. I have in fact 2 such motherboards but this comes later. I don't remember how Diablo performed on my older systems. But it's not Diablo, it's all games. All games experience stutter at certain intervals. This is not "regular" but it happens now and then. Often enough that you can say it always happens. So I am talking about Diablo 2, Diablo 3 and Overwatch. Both Diablo 2 and 3 have the same kind of 'stutter' where the game freezes for a slight second. In Diablo 2 this is not that bad that it renders the game unplayable, in Overwatch it kinda is. I have factually: - exchanged the CPU several times - exchanged the motherboard with a different AM2+ chipset. - exchanged the graphics card with a different brand. - exchanged the monitor and the monitor connection method (VGA/DVI -> HDMI) - exchanged the RAM with other DDR2 memory unfortunately also running at 800 MHz - even installed Windows 10 fresh on a SSD with the regular harddisk not connected. The only thing I have not changed is the PSU. At first I was completely blaming Overwatch and... I don't know. But recently I have been playing Diablo 2 a lot and... this stutter is always there. Most usually when something "bigger" happens like a big skill or moment is activated and at that precise moment the game will halt for a second. Well smaller than a second, but still very noticable. Not that it endangers my hardcore character, but it does so on Overwatch of course. But the interesting part about Diablo is that it has an fps counter with "frames dropped" information and also a much less demanding game. So how on earth can my system with all components replaced keep exhibiting the same behaviour in Windows 10, unless: - it is a Windows 10 problem - it is a Windows 10 problem with my chipsets (both AMD 770/SB600 and nVidia nForce 570 Ultra -- not that these precise chipsets matter at this point) - the PSU is faulty that I've had since forever and never had a problem with before (at least not during all of my WoW gameplay -- but I haven't tested WoW recently). I have tried running Diablo 2 in Windows XP or 7 compatibility mode but no difference. So I have a GTX 950 and a R9 380 that both should be running fine and have been running fine in another system. Unless, again, there is an issue with the motherboard chipset combination with these cards. The only thing I can try is take an older GT 640 out of the box and see what happens. Not feasible for Overwatch, but certainly for testing Diablo. I have tested multiplayer and single player, same thing. My biggest question to you now is: My FPS is displayed at 25 but there is also a figure of 19-20 frame drop. Is this normal?
