then, since 13.12 have no issues to enable crossfire...
i have 3 monitors: 2 on 1st card - 1 on the 2nd
if i enable crossfire sometimes the system hangs and i have to reboot
other times it turns on the monitor on the 2nd card only! (that is the exact opposite compared to what it should do)

is it a beta? OK BUT
why someone should be forced to revert drivers, just to test Mantle?
here i'm not talking about performance or optimizations, but basic functions...

this means that they touched something that was not to be touched... or the two paths had to be different... an untouched section reserved to D3D and another to Mantle properly (e.g. i want to test crossfire with Mantle - if it works - until it will be stable... or i want to do crossfire as usual with D3D with no problem, since 13.12 don't have this issue)

even if this 14.1 is a beta... i don't understand the reason to involve issues with D3D too... biggrin.gif

they have to start paying more attention...


ok first off why are you using ports off second card this could cause serious issues use the display port / HDMI off first main card other monitors are attached to remember the DVI ports on the 290X / 290 are dual port DVI and can handle 2 screens per DVI but requires a special adapter to do so. I would recomend using the HDMI port with a HDMI to DVI adapter at the monitor end to run your 3rd monitor alot cheaper than active display port adapter and keeps image quality same as other monitors attached to the DVI ports on the first card. These go for all the upper end GCN cards including hd 7850/7870 7950/7970 so they apply to your crossfire 7850's also.

A single R9 290X or 290 can do upto 6 screens / monitors at one time in eyefinity or individually.

here is a dual port DVI adapter first one I seen on the search page lol http://www.trademoon.com/product.asp?itemid=146211&gclid=ckoqkinqv7wcfezj7aodnuwarg allows one DVI port to run 2 screens. to show you the different DVI connections http://superuser.com/questions/440159/can-a-single-link-dvi-cable-be-connected-to-a-dual-link-dvi-port

sorry, but it's not true 'cause 13.12 have no issues...
the correct behavior is that, enabling crossfire, it only turns off the screen on the 2nd card...thing that it correctly does with 13.12

so it's all about drivers... i can choose to connect the display where i want... but i know that if on the 2nd card it will be off when crossfire enabled... easy thumb.gif (but not the opposite)

yes but proper orientation is to run all your screens off your main card otherwise it causes a possible conflict within your OS thru device manager which can cause all kinds of irradic issues as far as driver errors and hardware errors which could drastically impact performance of entire computer especially when running crossfire.

I want to point out the OS adds a driver for each monitor connected when using a monitor attached to the second card this can cause driver conflicts within the graphics driver and monitor drivers inside of device manager remember your graphics driver also locates attached monitors along with OS also does to install the proper driver for monitor itself and to set proper refresh rate / resolution of attached monitors.

I found the Mantle Beta drivers to be completely Crap on my setup. I cannot even play 30 seconds of Battlefield 4 without crashing, Freezing, or locking up completely. Had to revert back to 13.12.

I bet if you play with head a slight bit farther away jaggies will go away remember this if you cannot hardly see past edges of screen while gaming with your normal peripheral vision you are to close ask a eye doctor and they will tell you the screen should only use upto around 50% of your forward setting peripheral vision per monitor if you are seeing more monitor than this you are doing damage to your eyes and causing intense eye strain.
Are you for real? Completely untrue that display surface is what harms your eyes the total light intake of your eyes is important which makes display surface AND brightness the main criteria. I have sat in front of a 39 inch at normal brightness comfortable for quite some time while a 22 inch monitor with the backlight turned up did cause eye strain in a matter of minutes.

The 39 was pretty much filling my peripheral vision at 60cm I sat 80cm from it. I would say that I was about 50cm from the 22 inch and it filled about half of my vision.

I dont know if its just me but I was getting solid 60+ with 14.1 on high+150% uber sampling but now with 13.12 it wont go above 40. I have to put everything on LOW to get barely above 60+(I switched to 13.12 cause of sound bug and freezing) Before that I was using 13.11 Beta 9.5

Just because you had a specific experience with one specific monitor doesnt change what an eye doctor recommends facts are what I said before something to do with the focusing of your eye causing eye strain when you are focusing specifically entire site of view vs only 50% of main site of view for reading and such otherwise people would read books 6-12 inches from theyre faces which they dont for same reasons. Facts again doctors say it causes eye strain even reading a book to close to your eyes now a computer screen is far larger than a book so imagine the distance you read a book at from distance you use a computer screen both are same principle except monitor is larger so requires more distance according to an eye doctor.

Set your brightness to max for a day and see which was more exhausting the one with the normal backlight or with the maxed brightness. You'll most likely experience more eye strain on the one with the brightness turned to the max but again maybe you're a special case.

Did you have a better framerate before if not best thing to do is to use DDU and retry.

Mantle is stable - (BF4 isnt stable)

Starswarm benchmark
RTS - low --> CPU bottleneck
Mantle
i3 4330 60 FPS 3.5Ghz
FX 4300 62 FPS 3.5Ghz

directX
Fx 4300 21 FPS 4.1Ghz

Great boost!

citing eye-doctors, w/o documentation.

I'll take my own personal experiences, over this phantom eye doctor.
