QWEEDDYZ: Keep in mind - refreshrate is not related to FPS and "this game not support refreshrate" is wrong words. Well, it is right actually. But this is not related to what FPS supported. Refreshrate (Hz) is refreshrate. Response time is response time (ms). FPS is FPS (frames-per-second).
FPS ALWAYS affect game and physics speed.

There is reports (ofc mistakes always possible) that this game - TQ: Immortal Throne Gold - is work on 120 FPS. So probably force game to use 120 FPS should be ok. if some strange things still happening - force game to 60 FPS. You still got advantages of high refreshrate+low response time display (or HD TV). Display is display after all.

Vsync nowadays should be turned off permanently. Maybe some gsync-etc with choose how much fps should be. Video drivers allow to limit FPS without limiting refreshrtate (because it not the same things).
Or some 3rd party software. Sometimes (very rare) they required to force game to slowdown FPS.

But mostly turning off Vsync and use ingame limiters should be OK for most games. Sometimes video driver.

UPD: PCGW say something about game speed isuues on high framrate but not say anything conrete for original IT. Also there link to 120hz support (wrongly described as 120 supported too).
TQ Aniversasy Edition wiki article clearly say that FPS should be strickted to 60 to avoid glitches.

So it is. Game normal FPS is stable 60, not stable 120 or more. Refreshrate can be any else. It can cause some graphical glitches (horizontal lines screen desync) (not very noticable actually, it not like interlacing) or not. For perfect screen image refreshrate should be same as FPS (and you still get avantages even in that case, but not same as on high framerate) - and not FPS same as refreshrate.

Just chosoe what you prefer more - less "lacing" image (not so criticaly noticable) or higher refresharate. My opinion - second is better. If there is no problem in game - more refreshrate and more FPS is better. Maximum refreshrate, but still limited FPS - just differ numbers for each game.

Using vsync will increase FPS nowadays with high refreshrate displays. Should be turned off.

QWEEDDYZ: I dont think they can do much of this. Even for AE that technically a little bit differ engine. Ofc better implement FPS switcher to ingame settings. maybe there is not so big issues of 120 FPS.
They can force game to 60 FPS. But using Vsync broke this back again.

Yes. Originally Vsync intended to limit FPS to 60 hz refreshrate to got 60 FPS. Thats it. FPS should be limited. And Vsunc is one of the solutions to do that. But now with more and more "faster" displays Vsync is outdated thing. Now it can increase FPS to 120\144\280 even if ingame originally limit FPS to 60 and do not give chose of fps\vsync limits.
There is more modern things in current videodrivers. They for, again, correctly limit FPS and not to increase. But now it usually used by noobs (and streamers who worse than any lamo) to force games work as much faster as possible. And that always lead to ingame glitches (especially for streamers with desync fps in game\capture\stream apps).

Swissy88: Zzz..
Games that have their speed tied to FPS should be put feet first into a woodchipper.
Thanks for posting, not dealing with this bs.

Links: No need to do that. In the Nvidia control panel:

- Go to the options 3D Settings \ Manage 3D Settings \ Program Settings tab

- Select Titan Quest's executable from the drop down menu or press the Add button and point to it if it is not at the menu

- Go down the options until Preferred refresh rate... and select Application-controlled from that option's drop down menu

- Press the Apply button on the lower right of the window, and it's done.

You do not have to manually change anything before running the game, and the game should always run at its needed refresh rate, without affecting the performance of graphics card or monitor in any other application.

novumZ: My Issue is that I can run dx9 version fine with my g-sync monitor fine but dx11 version hasn't been updated in titan quest for g-sync so it doesn't run smooth; screen tears etc..,even with v-sync
Grim Dawn runs fine from the start.

To Dev: Please give some love to this game. Because Grim Dawn is way ahead of it with technical, thank you!

Deimos_Fresh: Devs probably don't read GOG forums. But you can try to contact TQH Nordic's support to forvard your request. I did it some time ago adressing problems about FPS and some other stuff. And since at least one of my problems was solved, I believe they do forward our mails.

This is what they respond to me with my request:

"Thank you for the mail.
We will forward your request to our Production department.
Unfortunately we don't know anything about future titles/patches/DLC-s or bug fixes but any client request and feedback about our titles are taken seriously and will be debated.".

MedeaFleecestealer: Please report any such problems here

https://redmine.thqnordic.com/projects/titan-quest-eternal-embers-community/issues/new

novumZ: This IS GOG!
I report here!

MedeaFleecestealer: Then don't expect to get it fixed. The devs have the place where they want bug reports to be made, if you don't want to use it, then don't complain if it doesn't get fixed.
