MY PC DO 33 FPS in THIEF 4 Benchmark test. if i did nothing to it, it was 15 FPS, maybe you could make your Thief4 faster. I have been testing a lot of config before this and this was the most stable non visual change setting. Find file "BaseEngine.ini" file and edit the following lines. (Mine was found in e:\StreamApps\common\Thief\Engine\Config\BaseEngine.ini) LINE TO BE CHANGED > TO ; SPEED UP GAMEPLAY TIP WITH NO VISUAL CHANGE. > Set BaseEngine.ini to "Read-Only" after changed it. MotionBlur=True > MotionBlur=False ; Verified OK Disable motion blur MotionBlurPause=True > MotionBlurPause=False ; Verified OK AllowRadialBlur=True > AllowRadialBlur=False ; Verified OK Adds shadows on existing objects Bloom=True > Bloom=False ; Verified OK UseHighQualityBloom=True > UseHighQualityBloom=False ; Verified OK There is one thing more. When you start THIEF 4 a Menu shows up, select OPTIONS right away and mark/use/tick "32-bit" mode. Then you are ready to start the game itself. I use resolution 1280x720, Tripple buffer, "Exclusive fullscreen", "Fullscreen", Preset "Very low". I was not able to add this to http://forums.thedar...4-tweaks-fixes/ it was locked. I maked the account yesterday. I just have to give you this advice because it seems like the game really start to get speedy. My PC/MACHINE is an not the fastest, I buyed it 2008 2x2.2GHZ Intel Processor 4GB ram(800Mhz) ASUS Nvidia Geforce GTX 750 Ti (the graphics without the 6 pin powersupply) very new graphics and QUIET card, Settings to Performance. Windows8.1 64-bit SSD When first running the THIEF 4 at the start I got 15 FPS maximum in Benchmark in thief4. (What the hell Tom raider & GRID2 = 60FPS) Changed everything in Nividia controlpanel global settings to "Primary screen" NO ENERGY SAVING mode. Performance mode. No "Make it more quality" settings. Then i got 25FPS maximum. And after "BaseEngine.ini" was changed saved and "write-protected". And before game start in options "32bit-mode" selected. I finally got 33fps with is pretty much better. I hope i help someone make thief4 playable. /Jetpack5
