Hello. I have peculiar question regarding BF1, fraps recording, GTX 970 and Radeon 7950.
Long story short, I did a quick fraps recorded gameplay video at Ultra settings on my GTX 970@1.5Ghz+2500k. Nothing serious. Just a quick browsing through the level, showing that the 970 can easily keep a steady 60fps with some cycles to spare, even with fraps recording which is not the best way to show performance (no software recording method is).
I tried to do the same for my 7950@1.1Ghz, which was also very capable running the game at 60fps, but when the recording started the framerate was dropping to less than 30fps.
The gpu load was still at 99% according to MSI Afterburner. It was the recording itself that tanked the performance. It was not the HDD speed, it was not the SSD speed and it was not the cpu speed. If it was any of them, the gpu load would drop, due to gpu cycles being wasted. So what was it?
For anyone interested however, 970@1.5Ghz and 7950@1.1Ghz seemed to have a carbon copy performance as my
Star Wars Battlefront benhcmarks. Maybe a little lower since I couldn't do proper benchmarks at the time.
I only tested DX12 on the 7950 and the performance dropped to around 50s.
