Solution thanks to @BitVenom and @tomasdegutis :
Lower texture size and especially texture quality settings.
Explanation:
High texture quality settings lead to high VRAM demands - too high for my 560GTX (1GB). For a more detailed and technical explanation and pointers to solving these kinds of problems and general awesomeness read especially @BitVenom 's posts below.
Hi community
just bought the game. Instead of having fun, I was battling with strange framedrops and the graphics options.
The problem:
The short:
I get good frame rates on high settings one time. After restarting the game, I get very low framerates with laggy mouse control. This may also happen after loading a save. The graphics options do not influence this. I can also have good frame rates after restarting the campaign but bad frame rates in the same session after loading a save state. I can also have a cut scene (e.g. Agnus dei flyby) with low frame rates and the game afterwards may have a good frame rate.
The long:
I start the game HW:R 1, put most of the graphics options to max (8k textures, textures on 9, vsync on, shadows on, lighting on max, HDR on, AA on 4) and start mission 1 of the campaign. Agnus dei plays, flyby of mothership - I am impressed, I really like this, everything is smooth
I play until you have to test the salvage corvette⦠and my fighters accidentally kill the target for the corvette. Mission control tells me it will send another target. Target never arrives (probably a bug). Mission incompletable. I close the game and do something else.
Later: I start the game again, start mission 1 again, Agnus Dei starts playing , huge framedrops during the flyby, the mouse control is very choppy, game is unplayable (Windows task manager: CPU at 45-50%, GPU temp normal, CPU core temps slightly above normal values for my system 60-65C but still ok).
I play around with the options and nothing helps, (vsync on&off, shadows on&off, AA none, 2 ,4 8). I restart the PC. Restart the game, everything works again. Campaign mission one 1⦠bla⦠everything works. In order to test if everything really works now, I close the game again and restart it, and load mission 1 (from a savestate), again low framerate and choppy mouse control.
I will play around with it a bit but I hope someone here can help. Thanks a lot for your help.
Edit: Restarting the pc does not always help - so no virus or other stuff running in the background. Anti virus program on and off tested, makes no difference.
Maybe certain graphic options (like vsync or shadows) need a restart of the game or reload of the map?
Edit: Steam or Homeworld keeps on changing the gameās language from English to system default which is very strange - I had to change it back 3 times already.
Edit: Off to new try⦠Quit game, start game, restart mission 1 Campaign , Agnus Dei flyby still choppy, so I skip it via the ESC key , BUT the game is completely stable with high settings (Vsync on, AA4x, shadows on etc., 8k textures on 9). I go back to main menu and load the a save from the choppy last time . Game is choppy again. I donāt get thisā¦
P.S.: The bug in mission one which renders it incompletable (see above) may also need to be adressed.
My system:
i5 3570k, 8 gb RAM, GTX 560, onboard sound, game installed on SSD
