am i gpu bound with this card?

probably yes, the card was considered a budget gaming card two years ago.

that's based on fact that my gtx780 is one third faster than yours and can barely display most effects on average settings with 30fps on single player. although your card should be able to display effects on low settings.

please don't shoot the messenger :)

I play on all maxed out settings, 60+ fps all the time, except the times when there are lots of particles, for a game of this age thats bad optimization of game engine i guess.

I actually tried playing with shadows off and all settings on lowest possible setting and the thing is, the issues repeat themselves on any video setting.

So in the end, i can do nothing, right? I can wait for more performance improvements from GGG side, or buy a new pc that will probably have same issues?

GPU of yours is more than enough for POE. Install and configure with on screen display MSI Afterburner and check the usage of GPU and CPU. I bet that your gpu wont utilize more than 50% usage.

yep, it's just some graphic effects that slow things down like burning /icy ground while the rest runs fine if you don't play in parties with massive skill effects.

good idea to check gpu load, you can also use a tool like gpu-z, it doesn't need to be installed and it's free.

I have disabled multithreading options in graphics options due to unplayable sttutering.

yep, forgot that there is a option now...

Allright, ive managed to fix most of my issues with POE sttutering (multithreading), low fps and etc. The problem was V-Sync, without it my average frame time went down to 14 ms. There are occacsionally spikes, but i can play even with multithreading enabled. I am using frame limiter built in MSI Afterburner and capped it at 70 FPS, everything is fine now. You should definetly try it, if you are expiriencing issues with V-Sync on.

sorry for necro'ing an old thread, but I'm having the same problems (water, fire effects causing frametime spikes making the game feel like running at 30fps while the fps meter says 60-75 (my display mhz).

I've tried some of the suggested things like disabling multicore (is a must), disabling various cores manually, power profile and of course used all combinations of settings like vsync (adaptive best results). UNTIL... I discovered when I set background fps cap and switched out of the game, standing in a scene that caused super sluggish fps IN SCALED DOWN RESOLUTION MODE, I noticed the game run fucking smooth (in HIGH RESOLUTION). Sure enough, I set foreground fps cap to 30 (vsync off) and it's smooth (30 fps I guess, feels like 60 compared to the 60 the fps meter reported before but felt like 30). Can't trust that fps meter. Actually I could crank it up to 50 without getting dips anymore. Feels much better than before.

Now I don't know if that's a solution because 90% of the time the game runs fine at real 75fps but if you want some sort of consistent moderately high fps without dips fps cap might be an option.
