I just picked up a new samsung 4k tv for my pc. Tried playing skyrim (not special edition) and now it is stuck at 30fps. Radeon pro does nothing (never gotten it to work at all). Changing resolution doesn't help. I was getting constant 60 fps on my old 1080p tv on the same settings.

I can run forza horizon 3 at 60+ fps at 2560x1440 on the new tv.

As a side note amd raptr opens so small on my screen i can hardly read anything and it will not go any bigger.

I have it in my sig but apparently its not showing up.
My pc is custom.
I have an i5 4690k @4.5ghz, sapphire nitro r9 390 8gb @1040 mhz and 16 gb ram at 1600.

From searching i think it may be my hdmi cable. Not sure what i have currently but i dont believe it is hdmi 2.0. It seems all games running at 4k are capped at 30fps currently. Im going to buy a new cable to test this.


I started up skyrim se and am running it on 2560x1440 at 60 on ultra no problem as well, at 4k it stayed at 30fps.

Sorry about that, Rob. Your signature shows up perfectly well - I'm just blind as a bat, apparently.

According to this Intel ARK resource:
http://ark.intel.com/products/80811/Intel-Core-i5-4690K-Processor-6M-Cache-up-to-3_90-GHz

... you can expect 4K resolution @ 24Hz via HDMI 1.4 or 4K @ 60Hz via the display port.

HDMI 2.0 allows for 4K @ 50/60Hz, but from this HDMI guide:
http://www.hdmi.org/manufacturer/hdmi_2_0/hdmi_2_0_faq.aspx#121

... it requires the firmware (CPU) to support this new standard. And your Haswell i5 only supports HDMI 1.4.

The way I see it, you need to find an Intel CPU that supports HDMI 2.0 or get a DP cable and use the display port on the R9.

Best of luck,
GreyCatz.

No worries about being blind, i have the same problem all too often.

Thanks for the info about my cpu, i was unaware that had an effect on the resolution. Wish id seen your post earlier, just got home with an hdmi 2.0 cable (and a bigger tv lol) and as you said its still at 30fps. Ill try to get back to the store to find a display port cable.

Didn't see that i accidentally chose your first response as the answer.... Gotta be a little more careful i guess.
