Re: Im having problems with crossfire r9 290x's 2nd GPU hardly being utilized

Just tested on 3d mark fire strike and got a score of 8527 with single gpu

And a score of 10010 with 2 gpus crossfire x enabled. but significantly more stuttering than with just one gpu

Same problem occurred 100% utilized on single gpu

while dual gpu settings same. first gpu 100% utilized second gpu 5-10 percent being utilized

If anyone out there knows the problem or solution please do tell me and save me from this problem.

Radeon Software Version - 15.12

Radeon Software Edition - Crimson

Graphics Chipset - AMD Radeon R9 200 Series( Gigabyte r9 290x 2 of them )

Memory Size - 4096 MB

Memory Type - GDDR5

Core Clock - 1040 MHz

Windows Version - Windows 10

System Memory - 32 GB (at 1600 mhz)

CPU Type - Intel(R) Core(TM) i7-4790K CPU @ 4.50GHz

PSU - 1300 watt G2 from evga

Mother board - asus maximus VI formula LGA 1150 intel Z87

This is a desktop

Yes full screen mode is enabled for all of my testing

From the past 2 posts of mine

Both GPU's are registered as active

Once testing starts first GPU is able to run at full 100% while the other is only working about 1/6th as hard as the first GPU.

It doesnt matter if i switch them one always ends up being used 100% while the other only about 5-10 percent

A quote from my 2nd post

Just tested on 3d mark fire strike and got a score of 8527 with single gpu

And a score of 10010 with 2 gpus crossfire x enabled. but significantly more stuttering than with just one gpu

I see people with the same exact setup as mine and they are able to hit upwards of 16-17000 on fire strike

Side note Global settings are

Anti-aliasing mode - application setting

anti-aliasing method - multisampling

morphological filtering - off

anisotropic filtering mode - use application settings

texture filtering quality - standard

surface format optimization - on

wait for vertical refresh  - off unless application specifies

openGL triple buffering  - off

shader cache - AMD optimized

tessellation mode - AMD optimized

frame pacing  - on

frame rate target control - off

Everything is basically stock nothing has been changed

Re: Im having problems with crossfire r9 290x's 2nd GPU hardly being utilized

Please uninstall 15.12 Crimson drivers. Download DDU and allow it to clean and restart your pc in safe mode.

Download 161.1. Hotfix driver to see if that resolves the issue.

If it does not, i would recommend trying Catalyst 15.11.1 Beta or Catalyst 15.7.1.
