Saphire HD 7850 OC poor performance in Starcraft II

post #1 of 22
Thread Starter 
Hello this are my specs:

Saphire HD 7850 OC (at default OC)
i5 2500k (turbo enabled, i.e. 3.7 ghz while gaming)
16 GB Corsair Vegeance @ 1333 (but can activate XPS for 1600 but would this really help at all?)
Maximus IV Gene-z/Gen 3 Motherboard
Blue Caviar WD 500 GB
Seasonic Semi Modular 620 W PSU

I am running absolutely everything in Ultra in Starcraft 2 at 1920 x 1080 resolution, and I have catalyst center version 12.4 everything at default settings, so no AA.

I am getting very poor frame rates during simple 1 vs 1 ladder matches, it will start at around 150-200 fps, then towards mid game I will have some sudden fps spikes to 30 fps, and at some point I was getting fps spikes to ONE fps!, which seems to happen whenever many sounds are playing at once, like for example 10 overlords popping at once and making the sound. This only seems to happen on the first game. The 1 fps has also only happened two times and I haven't seen it again, however the 30 fps seems to happen on the mid game at least once every game.

Towards end-game at 200 vs 200, I will be averaging 50 fps just by looking not even moving units or a bunch of buildings, durings fights it will average about 45 and extreme fights to high 30s even. I find this odd specially when this card is supposed to be in the 100 average with everything on ultra, so unless the testing is done on the start of the game, which I don't think so, I find this numbers low.

This seems kinda odd considering SC II is not supposed to be a demanding game, unfortunately I do not really play any new games to test, so all I could test was Guild Wars everything max and 4 x AA, it plays fine even when 200 + chars in town.

All my components are brand new, and I just assembled my PC 15 days ago, have not had any issues of any kind, BSOD or strange behavior, except once I turned the computer on a cold start, it started for 3 seconds and then reset itself and started fine (this was 7 days ago), I found that odd but has only happened once, and I had this problems since day one. So I am not sure what happened that one time, but I guess it was just a random fluke in power or something, I have of course everything connected to a APC @ 3500 joules.

I can run Prime 95 Blend test just fine, although I only ran it for 1:30 hours. My temps during gaming are GPU: 50, CPU: 55.

I am using the on-board sound on the Maximus IV Gene-z/Gen 3, I really don't know if this problem is related to sound or not though.

Does anyone else have a HD 7850 and plays SC II, what are your fps?

Other notes: It does play smooth overall even during large fights where it drops to 38-45 fps, however according to reviews it should be doing better.

Thank you,

Oscar

Maybe corrupt drivers? Reinstall drivers. Do you have 3dmark 11 or Uniheaven engine? Try running those

I am going to get one of those cards. I do hope the same doesn't happen to me

It could be corrupt drivers, since I did not experience the 1 fps drop before on 12.3, although I did have the random 30 fps drop on 12.3. However my fps average has always been the same regardless of CCC 12.3 or 12.4, the only difference I see is on early game I will get more average fps with CCC 12.4 than 12.3, but mid game and end game I average the same.

It says its comparable to similar systems, and I checked tomshardware, anandtech and it is slightly lower, but then again my cpu is only at 3.7 and my ram is at 1333, while their setups are 4.5k and also 8 virtual cores and ram at 1600 mhz +, so I assume my score is fine.

So it looks like the GPU is performing like it should, yet SC just won't play good enough.

Installing SCII now and will let you know how gameplay is. Your rig is quite a bit better than mine so I probably won't hit the same fps as you, but I can defo check for fps drops and such.

Using CCC 12.4 as well... no forced AA.
Runing SCII on ULTRA should be posible too smile.gif

What CPU cooler do u got? stock? Because your temps are quite high with that OC (none).
If Starcraft is like Starwars then your cpu clock could be the bottleneck.
You could try to raise it to 4.0 ghz and see if this changes anything...
I have the same setup (mobo and cpu) and with only a 30 dollar CM 212+ cooler u can raise your clock till 4.3Ghz @ 63 degrees celcius (room temp 20 degrees).
Im not into Starcraft but i assume u get that low fps in Multiplayer mode (something says me its only MP wink.gif )

Make sure CCC is set to application preference on everything. Ensure AA is not set to edge detect, make sure MLAA is not turned on. The bottom AA slider should be set to MSAA only, everything else application performance. Do not use any type of override, ever, except for very old games.

AMD makes it too easy to screw your IQ settings up, if you choose post process/SSAA in the CP it will destroy your performance. Other than that, I dunno. SC2 gets 100s of fps here and never dips.

Yeah, that's how my CCC is setup.

Back to the OP...
I've now been on SCII Multiplayer for nearly an hour straight now. I've had no significant fps drops at times where it shouldn't happen, and the fps drops that do occur are drops of 40fps in very heavy battles. On ULTRA settings my fps hasn't dropped to anything under 70fps. Measured by Fraps version 3.4.7, build 13809.

I've played 1vs1's and 2vs2's... using various armies.

I am at work atm, but I will check when I get home. I am using the stock cooler right now, but will probably get a 212 later.

As for the sound I believe ultra sets it to high by default, the textures are at ultra as well, I will confirm this once I get hone.

I will also check my CCC right now everythig is on default, is there anything at default that needs to be modified?, I think the config you mentioned are the default, but I am not sure.
