Just built a new PC and did a fresh install of Windows 11. This is the full spec:

i5-12400F
Gigabyte B660M GAMING DDR4 Motherboard
Crucial Ballistix 16GB DDR4-3200
Seasonic Core Gold GM-650 650W 80+ Gold
WD Black SN850 1TB SSD M.2 2280 NVME PCI-E Gen4 Solid State Drive
Gigabyte GeForce RTX 3070 Ti Gaming OC 8GB GDDR6X PCI-Express Graphics Card

Now I only game at 1080p but obviously I have a 144hz monitor. Admittedly I enabled the silent bios on the graphics card but even still surely I should be able to run max settings in a game like DoTA2 and maintain 144 fps with ease? It sits at 144 fps in the menu but as soon as I start a game it rarely hits 144, usually fluctuating between 115 and 130. I'm in the process of downloading Halo Infinite to see how that does.

Last game it dipped under 100 multiple times and average 110-120.

I'm not familiar with DoTA2 settings but for a lot of games there are some graphics settings towards the max end that don't add much but do demand a lot from the GPU. For example ultra shadows adds very little vs say high but may reduce fps by 3%. Multiple this by a number of settings and it starts to add up. Whatever game I play I try to find a deep dive analysis on the graphics settings to find the sweet spot.
 
I will have a play with it later but I'm reading that I should be able to get way in excess of 144 with no issues so shouldn't really have to worry about the settings. I'll also enable the OC bios instead of silent.
 
I wouldn't be surprised if its either got a software cap or something screwy with the way it uses the CPU thats causing this. probably not the GPU at all
 
Does it run ok in other games?

Ill agree with teh above post its probably the game not your hardware. You'll need to test it in other games, run benchmarks etc, judging it off one game alone is not much to go on.
 
Haven't had a chance yet, will try it tonight. What do you suggest to benchmark it using? I have used 3DMark in the past, a very long time ago and was surprised to see you have to pay for it now.

A single stick of memeory will hurt your memory bandwidth quite a lot, which in turn will cap your frame rates at lower resolutions where CPU and memory throughput make more difference than GPU power, Dota2 is source engine based I belieive which means it quite heavily relies on single core performance and is very likely quite sensitive to memory bandwidth and or latency much more so than it is to the GPU. You may very well find you get similiar performance at higher resolutions due to this. I wouldn't be too terribly surprised if you found that you didn't take much of a hit running it at 4K even.
 
The was the most affordable one with decent performance. It was 60 odd quid, guess I could stretch to another stick but think I'll see any tangible benefit?
