I stuck my old HD 5870 back in. It must be software related because now I can't play CoD with my old card.
In CoD, sitting still my FPS was 63 at maximum settings with the R9 290X. When I swung my cursor back and forth the FPS dropped to as low as 22.
In CoD, sitting still my FPS was at 45 at maximum settings with the HD 5870. When I swung my cursor back and forth the FPS dropped to as low as 15.
It might also be worth mentioning that booting up now seems like it takes a lot longer to do. Almost as if the "GPU Tweak" software that came with the card demands a lot of power to run.... Because it comes up on startup.
So I'm thinking it's software -
recent software - that's causing it because my old card never gave problems like this but now it is after I've put it back in the machine after having run the new one with new software.
Could it be the GPU driver? The GPU Tweak software? Maybe I need to max out the clock? :-D
Also, I ran the "Windows Experience Index" from the control panel. During the test, the GPU monitor (GPU Tweak) showed the card cycling from 0% to 100% for about one minute and the temperature ranged from 60 C to 70 C. I don't know if that's high, low, or about right.... Got a 6.1 base score out of a 1.0 to 7.9 scale.
Gonna power down and put the R9 back in now.
Thanks again for your patience and help!
