I believe a 2GB card is limited to Medium or High texture settings, which prevents it from using more VRAM and causes it to switch to a swap file.
what you received with your r9 270x is typical for that hardware. Running bf4 at stock speed usually caps around 24 fps, which is normal. Your fx6300 might not be powerful enough for smoother performance at full settings—especially with limited VRAM. Switching to lower or higher frame rates helps, but you still face stuttering when using the highest settings. Upgrading to a 3GB or 4GB card would make a big difference. After adjusting bf4 settings via user.cfg, you achieved around 35 fps with stable performance. That’s a positive result!
It looks like there are problems with 2GiB storage or GCN1.0 cards causing frame lag spikes. Using an older "phenom 2" 840 (an Athlon 2) helped a lot, and it improved my FPS on the 7870. However, occasional fps drops still occur.
