HELP! FX-8370 + 2x R9 280X Crossfire Poor FPS

[gendutz]

Hello friends,

I'm member from Indonesia. This is the first time I'm really desperate, and couldn't find the answer. This is why I thought you guys are my only last hope.

I'm an AMD fan (long story short, I was once disappointed by intel). Last year I build a new PC. For my daily work and Gaming purposes too. The only game that I play all the time is CS:GO.

My PC build:

1. PSU Enermax LEPA 80+ Gold 1000W Modular - G1000-MB
2. 2 x Samsung SSD 850 EVO 250GB
3. Motherboard MSI 990FXA Gaming
4. AMD FX-8370 4.0 Ghz Cache 4x2MB
5. Corsair Hydro Series H100i GTX Water Cooler
6. 16GB Corsair Vengeance DDR3 PC12800 Dual Channel
7. 2 x GPU PowerColor Radeon R9 280X TurboDuo OC 3 GB 384 Bit DDR5 (Crossfire)
8. BenQ 24" XL2411T
9. PC Case Corsair Obsidian 450D

I'm a PC enthusiast, I love building PC, but I don't understand technical. I don't understand OC too, so my pc still all stock. What bothers me is, even with Crossfire R9 280X, my fps very poor at CS:GO. Max only around 200+ fps, but very unstable. It went up and down very quickly. Average fps is around 150 fps, but in some map (especially WF maps), it could goes down to 50 fps. Video setting in CS:GO almost all high, only shadow detail is low, and shader detail also high, not ultra high. Multicore rendering enabled, texture filtering billinear, FXAA, VSync and blur all off. Also have activated -threads 8 at startup too.

Do CS:GO support multi gpu? This is very stressful for me. Did many research, but can't find the answer. I watched youtube, a single R9 280X already could reach 200+ fps range with similar video settings. What's wrong with my Crossfire? I once opened AMD Catalyst, and disabled the Crossfire. I played CS:GO, it seems like just the same as it's enabled.

I updated my driver to the new Crimson, and it's even worst. Often very laggy and jittery in games. So I downgraded to the latest Catalyst before Crimson, not all fixed, but at least a lot smoother and no jittery.

Yesterday, I almost bought new 980 Ti, but finally I postpone. I'm afraid if it resulted the same as my Crossfire 280X. This is driving me crazy!! Is Intel processor would be the solution? Any help, would be really appreciated. Thank you so very much.

Best regards,

Bobby

Check your CPU temps while gaming, its an AMD. Maybe thermal throttling because of overheating.

If you build a powerful gaming PC always go for Intel. (I get up to 500fps with an i5 3570k and a ati HD7870, lowest 350fps on nuke... and the cpu and gpu are older than 4years)

if it remember correctly the source engine doesnt support crossfire/sli. it is only using one card

That doesnt matter even 1 of his cards is very good. But source depends much more on CPU than GPU.

his card is the same card you have... its just a refresh

Oh ok, but I get more than 2x his FPS.

your cpu is more powerful but you could also be playing at different resolutions, settings, ect.

@OP: Resolution?

Thx for your reply

I don't think it's bcoz overheating. Coz even I just start up my PC and go play CS straight away, still the same problem. the fluctuation range very far. I have Corsair Link installed, when it's in gaming, it automatically full speed the fans when in high temp. btw may I ask what CPU that you're using? what setting? well for me, I use 1920 x 1080, with all the settings I mentioned above

At Dust 2, my fps could reach 200+, but if Wildfire maps like Tulip or Nuke, could go down until 50 ish. If CS:GO doesn't support multi GPU, so I better sell one

oh really?? if it's true, then it's problem solved. because as I said earlier, I was wondering why the one I watched on youtube with single GPU 280X, perform very similar to my dual GPU 280X. I was curious what's wrong with my CF. And yes the one on youtube is higher fps than mine, but he was using Intel. If really Intel is the one boosting the fps. so heavy bottleneck on my current cpu

you should try overclocking, i have the same cpu [well fx 8350] at 5.0ghz and it gave a huge fps boost.

try disabling crossfire ?

I never OC, don't understand anything about it. I once tried, and it hung. so since then I'm so afraid to try again. what country do you live in? Same weather as Indonesia? Will my Corsair Cooler could hold that high? And would you mind share the setting of all that you changed to reached 5.0 Ghz? Thx

well it's too late now. I have bought i7 6700K, MSI Z170A Gaming 5 and 16GB ram. Will try to assemble this weekend. Hope they will perform better than my current FX-8700K

thx bro
