Massive FPS drop during battles

ADV sequences play normally. When the first battle loaded, the pan across the map is like a slideshow, and even the mission conditions, text window, and end game popups lag terribly. The FPS is so low I don't think it'll even be playable at this rate.

Anyone else have this problem? I tried tinkering with the graphics configuration settings, both in the launcher and in-game, with no effect at all. My system is perfectly capable of handling modern 3D games (i5, Geforce 760, 8GB RAM), so I don't know what the issue is. I'm using Windows 10, but according to one of the product pages, this game should support Windows 10.

I tried a few cursory searches in Japanese and couldn't find any discussions on the topic. I also tried the software rendering (REF) option instead of hardware rendering (HAL) option in the launcher, but that throws a startup error.

Managed to solve this issue. The FPS drop disappears when the game is run in a Windows 7 32-bit virtual machine using VMware Workstation 12. I also tried a Windows XP virtual machine, but the game wouldn't even start, likely due to poor VMware support for DirectX in WinXP.

In short, this game's battle graphics engine isn't supported in Windows 10. That could be an issue if JAST looks into licensing it down the road.Last modified on 2016-09-06 at 00:44

2 years later. I got the same problem. So, the only solution is to use old Windows verions like windows 7 and XP? If someone can run this game on Windows 10 pls help!!!

So no way around the virtual machine? I wanted to play in windows 10 but the moment the first battle started it became unplayable. Lagging can't even comes close to what i saw.

I would try to run the game in compatibility mode and see if that fixes your problem.

So the issue is solved :D Or at least for me. And what did i do? Nothing. The first 2 battle is exactly like in the first post, lagging so much it's almost unplayable. But starting from the 3rd battle everthing is normal. totally playable. So i encourage everyone to just hold on till you reach the 3rd battle. The first 2 isn't terribly long either so just don't give up. I think the story will reward you enough later :D

How far did you play? Could be an intermittent issue throughout the game.

I can confirm that after the second battle. The third one becomes unexpectedly playable. I don't know if this problem will be encountered later in the game tho. Maybe because of the fog at the first 2 battles? The third one has a clear surrounding.

I can confirm that the FD version has the same problem. However, I don't know if it can be fixed after 2 battles like in this VN.Last modified on 2018-10-08 at 15:42
