Alright, that's very strange then. Battlefield 3, Crysis 2, and Trine are not exactly CPU bound games (well, BF3 can kinda be but it's very optimized) so if the problem was our CPU being a bottleneck we almost certainly wouldn't see it in those games. And yes, those other games you mentioned are GPU intensive, but they're also pretty CPU bound (perhaps with the exception of BF4).
I noticed you said you downloaded the latest drivers off of Intel's site, but you're using an AMD dedicated card. Those are the drivers you want to update. Have you used Catalyst Control Center or some other way to ensure your AMD drivers are up to date? That's extremely important,
especially because the R9 290 and R9 290X both had issues with throttling when they were first released. So yes, please make sure you download your AMD drivers. Intel drivers won't do anything for you except keep your Intel Integrated Graphics up to date, and those are pretty useless for a gaming rig.
thanks for the reply, yes i did update to the latest drivers using catalyst...still the same issue, but the weird thing twisting my mind is that benchmarks are totally normal, it only happens in games
Just last week I bought this model in Germany:
SAPPHIRE R9 290 TRI-X 4GB
I have exactly the same issues that you have. Overall, I almost never get the performance that can be expected from the benchmarks found on the internet. However, I blame the rest of my PC for that, as the CPU etc. are a little older and probably can't keep up with the R9 290. But thats ok imo. I mean, we are talking about 10% give or take less. That seems fine to me.
BUT: in Games. Totally different story. Although average fps again won't be able to match other scores found on the internet, there are two things that are worth worrying:
1. GPU usage fluctuates hugely between 100% and 0% every couple of seconds
2. probably as a result of the above, the framerates vary immensely. E.g. yesterday I played a couple of minutes Bioshock Infinite in ultra settings and run Fraps benchmark. Average FPS was almost 100 which seems fine to me. BUT, fps ranged from 7(!) to 198!!!!!! I'm sure you can imagine that if these kind of framerates switch every couple of seconds, the game becomes almost unplayable, despite the decent average fps.
I have found no solution so far. I just wrote an email to my reseller in Germany (Alternate.de) and asked for advice. If they cannot fix it, I'll probably go with a GTX770, which is most likely not as fast, but I'm sure it will just WORK.
btw: getting the R9 290 to work as it does now, was already quite an effort! Only drivers that finally worked were the new beta drivers from AMD and I had to specifially deinstall the old ones with a tool in safety mode. Moreover, GPU clock was fluctuating wildly and never ever reached its supposed clock of 957Mhz. I had to adjust the performance barrier in the Overdrive tool to +25% in order that it ran constantly at 957Mhz.
My conclusion so far: The card itself is great. Cooling is great. Noise is great. Performance potential is huge. BUT is just won't work properly. Bad job AMD.
