low fps and stuttering #253

Open dilandoc opened 6 years ago

dilandoc commented 6 years ago

Hi guys, thanks for one of best ever mods. Unfortunately in my pc it shows frequently frame drops in many game's location. These not seems caused by ingame settings (tryied to set lowest in all system ad vr settings) or driver settings. I also tryed to add some recomanded strings in vr_openvr.cfg ( rs_enable 0 and r_skipPostProcess 1), and reistall previous driver version, but nothing changed. The only other game that shows thats framedrops without solutions is Fallout 4 vr.

My configuration is: sapphire r9 390x with adrenalin 17.12.1 in windows 10 64bit build 1709 amd fx 9370 in crosshair 5 formula z 8gb ram dd3 1333hz crosshair xms psu cooler master 700w

I hope someone can help me...

I also noticed that gpu usage seems too low in game. Anyone can help?

Here is how to enable logging when starting the game:

Create a shortcut to Doom3BFGVR.exe Right click on the shortcut, go to properties. In the target field, add +set logFile 2 to the end - be sure to leave a space after .exe and before +set Click apply, then ok. Double click shortcut to launch the game.

Start a game, play for just a bit, then exit. The log file will be stored in c:\users(your user name)\saved games\id software\doom 3 bfg\base\qconsole.log

If you can put the log someplace like pastebin I'll take a look. ( a copy of the vr config files from the save game directory would be useful as well)

Thanks!

Edit:

Are you seeing stuttering and visually noticeable performance issues or just framedrops in the counter? Which headset are you using?

dilandoc commented 6 years ago

Thanks for answer me! The framerate falls from 90fps to 50-30fps in many situation(like the hangar at the beginning) so become unplayable in vr. I use htc vive. As soon as possible will send you the log file.

There are qconsole.log and vr_openvr.cfg found in saved game: https://pastebin.com/niKKtKDe https://pastebin.com/tAAZ4gpE

Didn't see anything noticeably wrong in the config. The dynamic lighting in D3 can actually be pretty tough in some scenes ( the initial hangar being one of them ) at the resolutions and framerates VR needs. With your card, lets start by disabling MSAA, and reducing the pixel density to 1.0 and see what difference that makes. Both of those options can be changed in the menus in game. You will need to restart the game after making the changes. Also make sure that soft shadows are disabled. If this makes a difference, you can try either enabling MSAA or slowly increasing the pixel density to improve image quality. It may not run well with both MSAA and a high supersampling (pixel density) value.

Let me know if this helps.

unfortunately I tjust tried to disable antialias, to set a very low value of pixel density (0.5 modified in cfg!), and many other cfg value, strangely without minimum changed. Only if I set r_lightScale 0 I have 90fps, but It is all blackout!

News! I tried in my laptop with win 10 + cpu intel i7hq + gpu nvidia 960M and the problem desappered, with better performance too. So seems to be a radeon supports lack. Maybe with the 0.22 update...

KozGit commented 6 years ago

One thing to remember is that AMD has not implemented asw/atw on the 390 series cards, which makes a huge difference. I don't know that I would expect a huge difference on that card in the upcoming version.

I'm surprised disabling MSAA and dropping the pixel density didn't help more. The mod by itself changes a lot of settings by default. You may want to try uninstalling everything, including configs on the save game dir, then reinstalling D3bfg it's default config, then the mod then disabling MSAA and reducing pixel density thru the menu to make sure all other settings are set to their default.
