Recording software takes 2D games framerate dramatically

The title is self explanatory, whenever I try to play games like Terraria and such things normally I get like 60 fps, when recording with ANY program like Dxtory, Fraps, and Bandicam i dip into the 20's, ive tried tweaking all the settings I could without compromising quality in some huge way like cutting the video quality in half or some crap like that, thing is I can play Garry's Mod, or Minecraft at 720p at a perfectly playable 40-50 when recording, it's brilliant, things like Deadbolt though seem to half the framerate for some reason. Why is this and should I upgrade to fix this??

Specs: Optiplex 380 (Slim i think) with a GT 210 in it

Hypothesis: 2D games from my understanding seem to be CPU based instead of GPU based, and since a lot of these recording softwares seem to be CPU intensive it is crippling the framerate, I think Shadowplay would help very well with this issue considering it is GPU based and very advanced only taking about 2% of the frames in most games, with CPU intensive games this would be a godsend.

(I will likely upgrade the CPU to a quad core processor and the GPU to a Zotac GTX 1050 ti so I can use shadowplay if that would help solve my issue)

  1. Terraria can only use a single core, only the lighting engine can take use of more threads. Considering that, any extra load on the processor will subtract from the single thread.

    1) 2D games aren't necessarily "CPU based" but if you do have a weak CPU, and use software that uses a lot of CPU then yes there won't be enough cycles left for the game and it plummets.

    2) NVidia Shadowplay as you say is your best choice once you upgrade. It uses the hardware encoder which doesn't require much CPU cycles so it shouldn't affect game performance much.

    Probably no more than 5%. Possibly NOTHING if using VSYNC (i.e. 60FPS for 60Hz monitor) and can still maintain a solid 60FPS.

    3) Just FYI but you may be able to MOVE your computer hardware to a cheap, ATX style case so you can use a normal graphics card.

    4) If you want CPU advice then tell us what you have. You can run CPU-Z, Speccy or other software to find the CPU model. Also useful to know version of Windows (i.e. W10 Home 64-bit) and how much system memory there is (i.e. 4GB).

    Good to know, im using the stock Core 2 Duo @2.9GHz im looking to double the cores and maintain around the same clock speed with a Core 2 Quad @2.8GHz both are still at 65W so from what I understand im just making gains

    I'm using 6 GB of memory, running windows 10 64-Bit, with a 300W PSU

    the issue with #3 though is the fact my computers layout is so completely off from normal PCs that you could say it's backwards, sideways, upside down and mirrored. the motherboard has NO chance of fitting in anything unless the case supports the extremely odd layout, getting a new motherboard will have to come first
