I have a dual core Pentium G850 and a 500GB HDD 7200rpm 16MB Cache. When I record with Minecraft, and it seems the same with other games, even with Cod4, and Black Ops 2 my Frame rates gets capped at 60FPS. However with Counter Strike Source when I record my FPS caps at 120FPS which is good and not 60 like almost every other game.
I did a test with Minecraft, when not recording the CPU usage was at around 70% (I do have other programs open such as Steam and Skype), when recording it stayed at abut 92% CPU usage and wouldn't go down than 92%. Is this too high when recording? Is it the processor or the hard drive causing the FPS cap? Would getting a secondary hard drive fix the problem?
It's HDD intensive also, if I got a Core i5 I probably still wouldn't be able to record well with an even FPS because my other PC that has a core i5 with one HDD that has 32mb cache (rather than this one with 16mb) can't record BO2 with a steady FPS.
