Hey guys, so I have this video card currently on my rig: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127512
and I currently use all lowest settings (even though all the suggested settings range from low to ultra). Yet, when viewing replays at 8x speed, i'll start off at around 50 or so FPS then drop to 15 towards mid-late game. Also, last night I was playing as zerg, and when i had a decent sized army of ling baneling muta on my screen i got 14 FPS. Yet I was playing today as protoss and had almost no FPS drop.
I did that variables.txt FPS limiter thing to get my FPS limited to 60 (yet ingame it shows 62), and 30 for menus.
Any idea why I am getting these gnarly FPS drops? This is a new rig I just built, and I enjoy playing on all lowest settings... It seems like it should be able to run it easy with no FPS drops..
|
without more information it is hard to say what is causing your fps drops, please post your specs..
|
got little to no ram? terrible cpu? theres a million different reasons why this could be happening.
|
Sounds like your CPU is not up to par. RTS games like SC2 depend more on the processor than the GPU.
|
|
are your drivers up to date? if you're using the newest one and getting this lag, you should try older versions
|
From the specs, I see nothing wrong for part selection:
mobo: BIOSTAR A880G+ AM3 AMD 880G HDMI Micro ATX AMD Motherboard psu: OCZ Fatal1ty OCZ550FTY 550W ATX12V v2.2 / EPS12V SLI Ready 80 PLUS Certified Modular Active PFC Power Supply cpu: AMD Phenom II X4 925 Deneb 2.8GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 95W Quad-Core Processor HDX925WFGIBOX ram: OCZ Signature 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model OCZ3SR1333LV4GK graphic: MSI N460GTX Cyclone 768D5/OC GeForce GTX 460 (Fermi) 768MB 192-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
I have a theoretically slower system than yours (C2D 2.66GHz and HD3870 graphic) but SC2 is smooth sailing on mine.
The only thing that I might want to check is the memory placement. From the mobo layout, when you have 2 ram installed it should be placed on slot 1 and 3. I had a weird experience with my friend rigs, he installed the ram at 1 & 3 where at his mobo it should be 1 & 2. It was problematic: restarting without reason, BSOD, won't start etc, but after I moved his ram to where it supposed to be, then all the problem is gone. RAM placement shouldn't be causing that much issue, but who knows?
And what is your O.S btw?

I'm not a tech expert, but low fps at 8x speed seems pretty normal to me. Even good rigs on low settings are gonna chug under that much stress.
|
Yeah, that's not odd at all if you're watching at x8 speed. Do you have background programs running at the same time? That's a lot of speed to process.
|
It is a known issue and Blizzard has acknowledged that there is a problem: http://us.battle.net/sc2/en/forum/topic/933154144
I have an i5/5770/4gb and can barely play on Low. Just post a summary of your problems and upload your specs in that thread.
|
Well it seems everything is up to snuff for the game, you have a pretty high end build. check if all drivers are up to date (download graphics driver straight from nvidia site), check if direct x is up to date too.
|
While this do not affect me at all I am still interested in the cause. Please make a topic when this is resolved
|
I'm interested in which SC2 recommended setting was "Low" instead of "Ultra". System should have recommended all "Ultra" with your specs. Might point us to your problem.
Make sure your power options is set to "Balanced" not "Power saver". Passive system cooling can kill even high end rigs.
Overclock your CPU and seeing if performance improves. It's the weakest part of your system.

Watching replays at high speed makes everything chug. It's highly CPU limited since the game needs to interpret the replay at a high speed. You could have a much more expensive video card and see the same results.
15 FPS is about what I get on an ATI 5850 and an i7 930 with high speed replays.
|
It's CPU limited. SC2 has a fixed-rate game engine, which therefore has eight times as much work to do per second at 8x acceleration. The speed is also heavily dependent on the number of units moving on the map, which is why zerg can be a lot slower than toss or terran.
I don't think any current CPU can run macro-heavy replays at 8x with a good frame rate.
