Bottleneck or what? i7 4790k@4.5Ghz and GTX 1080 FE

post #1 of 8
Thread Starter 
Hello, I would like to ask for help about this situation, there is a problem happening in The Witcher 3 where my GPU usage near the city, specially Novigrad is very low, like 70~80% most of the time in the middle of NPCs, I didn't have this problem with my previous GTX 980, do you guys think is bottleneck or something wrong with my system? By the way is a fresh Windows 10 Pro installation, only installed the game and Windows Updates, of course the newest driver 368.95 and MSI Afterburner. You guys can see in the video:

I saw other people videos with i7 6700k and even 5960X, the usage is very solid at 98~99%, I also overclocked to 4.8Ghz just to see if it would change something about the GPU usage but is the same.

Is your ram running 1600mhz as in your rig specs? You can easily overclock the memory and see if it helps.

Which other videos are you referring to? To be honest, the loading in your video doesn't look that unusual to me. You say 70-80, but it only hits the 70s momentarily twice.

That is pretty much the experience everyone has in Novigrad. A few tech review channels on YouTube even use a route through the city as their CPU bound test to compare processors and RAM speeds in games. Novigrad is the most CPU intensive area of the game because of just how much is going on around you and that's pretty normal to hit a slight bottleneck there. I have the same situation with my 5820K @ 4.515GHz and a 980ti at 1475. The CPU probably just falls a little behind processing game logic at the rate at which the 1080 can deliver new frames Getting the fastest RAM you can and pushing the clocks on your CPU might help a little bit but I wouldn't say anything is wrong at all.

My 4790K is at 4.7GHz with DDR3 at 2666MHz and 980 TI at 1480/8GHz. I get near full utilization at all times running in Novigrad, with blips only down to 92% for brief moments. Using 368.8.1 drivers as well.

It seems to me that you had a higher density of NPCs visible on screen, on average, than in those two videos (especially the second one).
