CPU: i7-7700k
GPU: RTX 3080ti 12gb FE
MB: asus rog strix b250i mini itx
Ram: 16gbs 3600mhz g.skill ripjaws v 3600 (16gb)
PSU: gold power supply 650w
I ran it on valorant too with the lowest settings and got 170-210fps which is almost the same as what my RTX 2070 did, but when I run it on COD Coldwar I get less fps than the 2070
also the CPU usage gets to 70% and the GPU usage gets to 40%
I need help!!!
 
Solution

This is 100% the issue.

Single channel RAM will slow down you CPU's ability to access the data in the RAM which in turn prevents it from pre-rendering frames fast enough and causes an artificial CPU bottleneck. (It's artificial in the sense that under ideal circumstances your CPU might be fast enough to feed your GPU the frames it needs, but due to your single stick of RAM, it is unable). Your PC sorely needs dual channel RAM: two identical sticks of RAM. Since you already have 1 x 16 GB, you will need to buy an identical 3600 MHz 16 GB stick of RAM. This will allow your CPU to work at its full potential and feed your GPU the frames it needs, increasing your GPU utilization and increasing your frame rate.
if its running at 40% power, then its not necesary

That is the worst excuse I've ever seen for skimping out on a PSU. You should NEVER do this PERIOD.

Always get over the amount of wattage for your system under 100% load for all components. As that can and will happen at some point in time.

The moment you skimp out on a PSU by getting a wattage below your maximum system load wattage requirement, you will be at high risk of bricking your entire computer.

Absolutely.

@ZomBeeZ Please try GPU-Z and check PerfCap reason and GPU load and frequency under load. Post here what you see.

This answer is not helpful, but There's a lot of complaints about the RTX 30 series GPUs now. A lot of people are having troubles with them.

lemmie just chime in with what others have mentioned before me here
3080ti generally needs a PSU that can cope with fairly high transient loads.
Most 650W PSU's can provide enough at full load. But hardly any of those
are equipped to cope with those nasty spikes.
