cpu/gpu bottleneck in nfs rivals?

[Karan Luniyal]

Hello everyone!
My pc specs:
Intel pentium dual core e5400 2.7 (oced to 3.7ghz)
Gpu : nvidia gtx 750 (oc)
Ram:ddr2 2gb (800mhz)
I know the cpu will bottleneck gpu but i still bought a 750 and oced cpu and played nfs run on ultra 30fps(it is locked by default).it was perfect 😀.
Yesterday i installed nfs rivals and ran it.
It was on 18-24 fps on ultra and same on low i play on 1366x768.
It was weird thay my gpu was 98% and cpu uaage was 100%.
I oced my gpu heavily.(bandwidth got 96gb sec and pixel 19gsec an txel were 59gbsec)
My gpu usage was still 98% (msi afterburner) and cpu 100%
And fps is same.what to do?
Is msi afterburner showing wrong usage?
And on utube people with hd7770 are running ultra 30fps.
Please help..
If cpu is bottlenecking gpu then why gpu usage is 98 or sometimes even 99.?

I would say your CPU is the bottleneck, as it is quite dated, and was a budget chip back in the day on top of it.

2GB of DDR2 RAM could easily be causing issues. On my Core 2 Quad rig I have 4GB of DDR2 and it's noticeable. I've seen many tests showing 8GB vs 4GB improved performance, so I can only imagine what upgrading from 2GB would do. See if you can find 4GB kit of DDR2 to replace your 2GB if the FPS fix linked by Singular9 doesn't improve matters for you.
