R9 270X Low fps with for instance World of Tanks

[Tijmen61]

So recently I bought an R9 270x from Sapphire, the Vapor X edition. I have got problems with my FPS, when I start playing I have got a good 40 fps on World of Tanks but after 1 game I have got around about 10 FPS. I do not think that the GPU is bottlenecking the CPU and I don't think it is because of the PSU. Can anybody please help me? Thanks in advance.

These are my specifications.

MB- Asus P7H55-M
CPU- Intel I3 540
Memory- 4 x 2 Gbytes 1067 Mhz
Storage- Seagate Barracuda 7200.8 300 Gbytes
GPU- Sapphire R9 270X Vapor X
PSU- HKC SZ-430 PDR 430 Watt +12V Max 15A
DVD Drive- Plextor PX-755 A
OS- Windows 8.1

Tell me if you need more information.

First, Check your temps, maybe the card overheats and downclocks.

Second, The chance that there is a bottleneck is very small as the first run the GPU worked perfectly fine.

The PSU might be the problem. And R9 270X can use quite a lot of power. I used to have a HD 7870 and it refused to work with a 450 Watt power supply (With A10-5800K). You also have a weaker brand so that might truely be the cause

Never heard of this game until reading your post, but I just looked at the official YouTube chanel for it. World of Tanks looks like a graphically intensive game!

My primary concern is the large amount of physics particles. Nothing in the documentation I've read just now shows that the physics simulation is GPU-based. Press ctrl+shift+esc to open task manager (performance tab) before you play in order to monitor your CPU usage. See whether it's high during the times you get these major frame drops that you have been experiencing. To see that just press alt+tab during the slow-down, and tab over to task manager. Is the CPU really high? If so, see whether there is a way for you to turn down the physics simulation in the options. The CPU is enough to feed your GPU, but it definitely isn't enough to run physics simulations at the same time. The recommended CPU on the game's website is an i5.

Your power supply is fully adequate. Your card has been tested to use only 230 watts under full load, which leaves 200 watts for everything else. Also, your card is not running at 100% full load during game play, so you will have enough power. If power were the issue, you'd either get a blue screen of death (BSOD) or else your machine would power down.

The 270x should be able to run this game if you pick the right combination of settings, and it should do it smoothly with fairly high detail.

Perhaps your RAM creates a bottleneck. Running Windows 8.1 with a graphically intensive game should have at least 8 GB of RAM in most cases. To see whether that rule of thumb applies to you, do the same thing as I described above by opening task manager. The performance tab will also tell you how much RAM you are using. Since the game only recommends 4GB, you might be okay on this front.

Nothing else should be an issue.

So you suggest buying new CPU, MB, RAM? By the way thanks for your reply.

Not yet. Just try the tests I mentioned in my first post and report back your findings. There is still a chance that you can get it running well on your machine, and there is no point to spending money before you know whether doing so's necessary.

CPU Utilization ___
RAM Uage ___
GPU Utilization___ (If you can get it. Try using MSI Afterburner to get readings.).

I have got MSI Afterburner, tomorrow I'll post the results.

Hmm, it doesn't seem to be an issue with your CPU or GPU. It also wouldn't make sense for it to be the RAM, though it does seem odd that your system is using so little RAM. Perhaps it's utilizing virtual RAM on the HDD in order to preserve system RAM. Running Windows takes nearly as much RAM as you're utilizing during gameplay. If the system is swapping out to the HDD in order to save RAM, it might be slowing things down. However, the system probably is not paging out given that you have 8 GB.

The only other thing that I can think of is that you may be seeing frame drops during times when the system is loading something off of the HDD. When a drive is the direct source of information, things will really slow down a whole lot. In game, that usually translates to little skips and blips. Check out this video comparison: http://www.youtube.com/watch?v=PriMnhNf56s

Other than that, though, I'm out of ideas. Not sure what else it could be.

Your CPU and GPU seem find, though, it does seem odd that your system is using so little RAM. Running Windows usually takes much, so there is a chance that your system is paging out some things to the HDD, which would slow down things considerably. However, I don't think that would make sense because you have 8 GB, so there would be little reason for the system to page out when using only 1/4 of the available RAM.

The only other thing that I can think of is that your HDD is slowing things down. When you run off an HDD in games, you can get little blips and hickups. Take a look at this comparison video to see for yourself: http://www.youtube.com/watch?v=PriMnhNf56s

Other than that, though, I am out of ideas. Good luck!

So I finally found the solution, my cpu was bottlenecking my gpu. What cpu would you guys suggest?

If you want to stick with your motherboard, the Intel i7-875k was a very good chip for the LGA1165 socket. Here are some e-bay listings

Thanks, but I think I will just upgrade Motherboard and CPU.

Thanks, but I think I will just upgrade Motherboard and CPU.

Great! The best four-core i5 and i7 right now are, respectively, i5-4690k and i7-4790k. They use the X97 chipset and LGA 1150 socket, so any motherboard with those specs will work. Both are great CPUs that will overclock and last several years. The i5 just lacks hyperthreading. So even though both are four-core CPUs, the 4790k will appear in your operating system as 8 cpus rather than 4.

If you need more processing power than that, you can go with the X79 chipset in order to get 6 core i7 CPUs. They cost a lot more, though.
