Frame rate shutter when enemies load out of no where, and during fights.

[Birdman]

My system shouldn't have an issue with this game, but I get a frame rate shutter on occastion. Anyone else having frame rate issues when enemies spawn, or during fights?

CPU: AMD FX-4100 3.8 Quad Turbo
GPU: GTX 560
RAM: G.Skill 8 GB Sniper Series 1866
HDD: 1 TB 7200 RPM

I had pretty heavy (<35fps) frame drops initially, especially in large battles and around fire. Most of these I managed to fix (or at least heavily improve) by dropping the Shadow quality in the game from Max to one setting below the Max.

My GPU isn't anywhere near maxed out in this game even with Max settings, but Core 0 on my CPU is heavily loaded while the others are barely touched. This means the game is heavily single-threaded and bottlenecks easily on the CPU.

I suspect they're running some of the graphics settings off the CPU instead of the GPU, which might explain why lowering the Shadows setting improved my framerate. Also there seem to be instances where the framerate just deteriorates over time for no reason.

As you can see below my CPU is hardly a slouch. So if I'm having this kind of trouble, I wonder what low low FPS are other people dipping to? It's certainly pretty bad for the sequel to a game that was so "low-end system friendly". :(

CPU: i5 2500k @ 4.2ghz
GPU: GTX 680
RAM: 8gb DDR3 @ 1333mhz
HDD: Samsung Spinpoint F1 7200 RPM
OS: Windows 7 64-bit
Resolution: 1680x1050

That makes sense because it's programmed for single CPUs it bottlenecks. I'm getting between 20-60 fps on 1920x1080, vsync, AA, and all settings maxed. I wonder if they'll come out with a patch to fix this issue. My GPU, CPU, and RAM should eat this game for breakfast, but I guess it's a problem with the software, not my rig. Thanks!

Multiple cores allow multi-tasking. These programs run on 1 core. Writing these programs to run on multiple cores would be senseless and hugely expensive. Multi-threading is a function of the core which is accessed by developers to process code. ALL multi-core processors support multi-threading "on a single core" (had to edit that in). That said, TorchLight 2 inordinately pressures my Intel i7 3.07 and it is possible they are using the CPU to process graphics. In any case, there certainly exists program inefficiencies.

Have you guys found a solution to this yet?

@Jack's Colon I responded to your question in the dead thread you resurrected, but now that I read this it seems like a multiplayer de-sync issue, since single-player games load the map with everything (including mobs' locations) before you enter it.

in which case, your rather good hardware spec has nothing to do with it, and your network bandwith (availiable for Torchlight 2 to use), ping and ports forwarded on your firewall (if you have one) need to be checked, as well as the connection on your friends' side since it's P2P.
read other "multiplayer problem/de-sync" threads on this forum.

as for single-core and CPU-bottleneck (also @Amarinth):
my CPU is beyond low-end - an 8-year-old single-core AMD Athlon 64 3000 @1.8Ghz - and it runs perfectly on single-player.
the resoluion I've set (1680x1050) doesn't even make my good old Radeon HD3650 hiccup.
this game is even more "low-end friendly" than Torchlight 1, which had me stuck in loading screens for 5 minutes.
they optimized the code to perfection.

stop using the term CPU-bottleneck. it makes you both sound stupid.
the CPU is the fastest component most PCs have. 2nd fastest if you have a monsterous GPU, but still of higher priority.
it takes a combination of bad programming, lousy OS AND heavy stuff running in the background to actually make a CPU bottleneck anything.

[Birdman]

Yeah, it has nothing to do with ping. Funny we sound stupid when Runic tech support said the same term when I explained this whole situtation to them, along with our discussions. Wrong vocab, maybe, but we're not stupid. I'll let you guys know as we email back and forth. They said Afterburer, or PrecisionX sometimes makes games run funky, especially when you overclock. I'm running stock; I just thought you guys should know. They also said some AMD processors are having a hard time with the game - mine's a AMD FX-4100 3.6 (3.9 Turbo). Peace fellas.

im running with an amd phenom ii x4 965 be 3.4 ghz and a asus nvidia gtx550 ti and 8gb ddr3 ram and maxed settings at 1920x1080 60fps steady not even a slight drop regardless of situation multiplayer or singleplayer very strange game it seems
**edit running on windows 8 pro 64 bit latest nvidia drivers

Okay, I tried something and it seemed to help my frame rate a lot. I disabled "real time protection" in Microsoft Security Essentials - disabling my antivirus, and then I quit out of PrecisionX, and ran my card at stock speeds. So far, my frame rate has stayed really high, even during fights.
