Which one is the bottlenecker ?

[Rekted]

I'm currently using an i5 4460 with

a Palit 750ti StormX Dual (specifically that card because the boost from FE is major). I received a lot of stutters in games like GTA and Shadow of Mordor so I want to check the usage and identify the bottlenecker but I saw both the usage of CPU and GPU was 100%. The games are in full screen and least as possible background tasks. I know the setup is a bit weak for big AAA titles but I'm upgrading in a year or two. How can I identify the bottlenecker?

Your issue doesn't sound like a bottleneck, it's probably your GPU running out of VRAM (the 750Ti only has 2GB of VRAM) or you are running out of system RAM.

Your GPU is the bottleneck.How much RAM do you have?

The sensor from afterburner reads approximately around 1900MB used, i thought the vram problems only happen when it exceeds

in gta you can sett the seting so that you dont use all of the Vram, i got the palit gtx 750 ti StormX oc (only has one fan) and with the settings set a specific way i get a stable 60fps. so maybe it is your CPU since gta is more CPU heavy

That is very close to the limit, I think you should start looking for a new GPU with at least 4GB.

it is close, but nothing to be a bottleneck, mine is running at 1997MB

Oh, major point, I am using the GTA Redux mod, I think that's the problem

yeah, that might be the problem. try it without and see if there is a big difference, but you probably knew that that's what you need to do now XD.

Thanks I'll try it out
