Edit: Turns out, the 12.10 driver has an odd issue with the GPU clocks not being completely stable. 12.11 beta drivers have fixed it. Woohoo! Original post is below. ---------- I apologize in advance if my problem sounds vague, but I will try to be as descriptive as possible. I recently built a new machine with an FX-8350, an MSI Twin Frozr 7870 (OC edition), 16GB of DDR3 1600 memory, etc, etc, but I'm a little disappointed right now: Many newer games feel "jerky" on my new PC. Despite getting decent framerates, there is an odd kind of microstuttering going on. Sleeping Dogs, Hitman: Absolution, and BF3 are currently the most notable offenders I can think of (I have yet to try all my games on the new build). I had another machine with a very similar setup, including a 7870, but it had an i5-2500k instead of an FX-8350. Sleeping dogs ran extremely smooth on my i5-2500k machine, but feels very "jerky" on my FX-8350 machine with the same settings. I don't understand it at all. Before we go any further: I understand that the i5-2500k beats out the FX-8350 in games by a fair bit. Let's just get that out of the way right now. I don't want to start a CPU debate. However, this should only make a difference in CPU bound games, shouldn't it? Sleeping Dogs is certainly not CPU bound. (correct me if I'm wrong.) You might say "Well, but BF3 multiplayer is actually CPU-bound." True, but I've joined completely empty BF3 servers with small maps and it makes no difference. The framerate jankyness/microstuttering is still there when running around in an empty level. Hitman: Absolution is probably the worst. I assure you, the stuttering is not because I'm running Hitman at unreasonable settings; Medium-High with 0xAA is not unreasonable at all for a 7870 at 1080p. I can certainly lower the settings for a better framerate, but it does nothing to fix the "jerkiness". Hitman Absolution is the most hanky janky of all. Based on the topic title, it sounds like I'm blaming it on the processor; in reality I'm not sure what's causing the stuttering. Rather than putting this in the CPUs forum, I feel it's more appropriate in VC&G because it's completely graphics/gaming related and I've yet to pinpoint the problem. You can see my build in my signature, but I'll write it down here for the record. This is what I'm using: AMD FX-8350 Processor MSI R7870 Twin Frozr 2GD5/OC G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM MSI 970A-G46 AM3+ AMD 970 Motherboard Kingston HyperX 3K SH103S3/120G 2.5" 120GB SSD SeaSonic M12II 620 Bronze 620W PSU Things I've done Freshly installed and updated Windows 7 x64 Fresh install of latest stable AMD drivers (12.10) Installed the latest AMD chipset drivers from MSI Updated the MSI motherboard's BIOS to latest version Set memory timings and voltage correctly in BIOS Changed PCI Express link state power management in Windows to "off" That's... all I can think of right now. I wish I could be more descriptive. I'm not as knowledgeable as some of the people here on AT, which is why I'm asking for advice here. What could be causing this annoying "micro-stuttering" I'm getting in my games? It's (kinda) subtle enough that many average gamers wouldn't notice it, but I 100% without a doubt notice the problem, and it definitely didn't exist when I was playing BF3/Sleeping Dogs on my i5-2500k machine. If need be, I can record an off-screen video showing the problem. I'd have to upload an uncompressed 60fps recording straight from my camera in order to see the effect.
