Evo par tweakova za PC igrače kako si mogu poboljšat izgled igre i performanse (preuzeo sa Witcher 3 Foruma):Tweak your GPU Control Panel settings for maximum performance and visual fidelityNOTE: The following applies to NVIDIA GPUs, but I'm sure there is an equivalent for AMD ones as well!For added in-game performance:Go to the NVIDIA Control Panel, then with the "Manage 3D settings" tab selected on the left side of the window, select "Program Settings", find "The Witcher 3 (witcher3.exe)" in the drop-down menu and edit the following variables:Power Management Mode: Prefer maximum performanceThreaded Optimization: OnClick the "Apply" button, then start The Witcher 3: Wild Hunt, go to the "Options" menu, then "Video" and select to render the game in "Fullscreen".Source: TheRaidenPTWhile still in the NVIDIA Control Panel, navigate to the "Set PhysX configuration" and choose to offload PhysX calculations to your CPU from the "Select a PhysX processor" drop-down menu. Then click on "Apply" and you should see a framerate improvement in-game!Source: UnrealEckFor added visual fidelity:Also tweak the following variables in The Witcher 3's "Program Settings" in the NVIDIA Control Panel to match the values below:Anisotropic filtering: 16xTexture Filtering - Quality: High qualityFinally, click the "Apply" button and you are good to go!Fix poor framerate and crashes with NVIDIA GPUs by disabling the NVIDIA Streamer ServiceIf you are using an NVIDIA GPU, then you are also likely using NVIDIA GeForce Experience. While the latter can be very useful for determining what settings your rig should lean towards, it also introduces a new service, called "NVIDIA Streamer Service", that is only used for streaming your games to SHIELD devices and is actually causing framerate issues in many recent games, including Grand Theft Auto V and The Witcher 3: Wild Hunt.To turn this unnecessary service completely off and regain your lost framerate, as well as prevent any associated crashes, click on the Start Button on the Windows taskbar, search for "Services" and then right-click on its icon and select "Run as administrator".After that, scroll down through the "Services (Local)" list, find and right-click on "NVIDIA Streamer Service", then select "Properties". First click on "Stop" to turn the service off and then select "Startup type: Disabled" from the drop-down menu.Source: TheRaidenPTIncrease texture quality by enabling higher quality mipsNavigate to "...DocumentsThe Witcher 3" and open the "user.settings" file with a text editor such as Notepad, then manually add the following section and variable at the very end:UseMipRefiner=trueThe addition of this variable will force the game to use much higher quality mip textures, improving the visual fidelity of the game at little to no performance cost! See it in action - ON, OFF.Remember to save your changes upon closing the "user.settings" file!Source: Asmodean778Set your maximum pre-rendered frames to "1" for increased gameplay smoothnessSeveral users have reported that the overall gameplay can be made noticeably smoother by setting your maximum pre-rendered frames to "1" in your GPU's Control Panel.For NVIDIA GPU users, open the NVIDIA Control Panel, then navigate to the "Manage 3D settings" tab, select "The Witcher 3 (witcher3.exe)" from the "Program settings" drop-down menu and modify the following variable:Maximum pre-rendered frames: 1Finally, click the "Apply" button and enjoy your smoother game!Sources: Slammey, Danikenbr and TheRaidenPTSet the "Witcher3.exe" process to "High Priority" in Task Manager to win some extra frames-per-secondIt would appear that The Witcher 3: Wild Hunt is not making effective use of CPU power and that setting the "Witcher3.exe" process to "High Affinity" in Task Manager can help alleviate this problem and win you some extra frames-per-second!With the game running, Alt-Tab back to the desktop and then press Ctrl-Alt-Del to bring up Task Manager. Find the "Witcher3.exe" process, right-click on it then select "Set Priority > High". After that, you can simply close Task Manager and Alt-Tab back into the game!Source: TheRaidenPTAlternatively, if you want the game to always run at a high priority, then open Notepad and copy/paste the following in a new .txt file:Windows Registry Editor Version 5.00 “CpuPriorityClass”=dwordThen save the file with the extension .reg (e.g. "witcher_priority.reg") wherever you want, double-click on it and select "Ok" to add the new key to your registry!Source: aidanrConfigure NVIDIA HairWorks for maximum performanceNavigate to "...The Witcher 3 Wild Huntbinconfigbase" and open "rendering.ini" with a text editor, then find and tweak the following variable:HairWorksAALevel=2 or 4Source: Da7miiManually tweak the game's graphics even furtherFirst of all, navigate to "...DocumentsThe Witcher 3" and backup your "user.settings", since it is this file that we are going to be working on! After making the backup, open "user.settings" with a text editor such as Notepad++, apply any of the tweaks below and save your changes when prompted. To make sure the game does not override any of your tweaks, right-click on your "user.settings" file, click on "Properties", then tick the box that says "Read-Only"!a) Detail Level TweaksIncreasing these parameters will improve the above Detail Level setting by increasing the visibility of decals:DecalsHideDistance= DynamicDecalsHideDistance= DimmerHideDistance= StripeHideDistance= SwarmHideDistance= Editing these variables will increase the chance of decals spawning (such as blood from sword wounds), as well as allow decals to spawn over larger distances:DecalsSpawnDistanceCutoff= DecalsChance= b) Foliage Quality TweaksThe following variable controls how many tress are visible on the horizon, but Andrew Burnes from NVIDIA suggests that it might actually be hard-locked:MaxVisibilityDepth= Increasing the following variable can increase the rendering quality and visibility of trees. However, the performance impact of this setting is significant and you might want to think twice before editing it further!FoliageDistanceScale= c) Grass Quality TweaksTweaking the following variables will lead to the increased visibility and fidelity of grass and shrubbery at a significant performance cost:GrassDistanceScale= The following variable controls the density of grass, at the expense of accurate placement. Its performance impact is insignificant, however:GrassGenerationEfficiency= - Increases amount of grass when value reducedGrass can be forced to render even more densely by tweaking the following value beyond its ultra setting, but at a significant performance cost and a loss in grass variety, as well:GrassDensity= d) Mipmap Bias TweakPatch v1.04 modified the "Texture Quality" setting to automatically introduce TextureMipBias tweaks on the "High" (-0.4) and "Ultra" (-1.0) levels. While this can improve the sharpness of textures, it comes at the cost of texture "shimmering", which can prove quite distracting to some.To revert back to patch v1.03's texture mip bias levels, tweak the following variable in your "user.settings" file:TextureMipBias=0Alternatively, if you do like the effect, you can try decreasing it to "-0.7" in order to strike a nice balance between texture sharpening and shimmering!e) Particle TweakTweaking the following variable can increase the amount of particles displayed on-screen, but Andrew Burnes' testing was not conclusive thus far:cvMaxAllowedParticlesCount= f) Shadow Quality TweaksBelow are all of the individual variables governed by the "Shadow Quality" setting in the in-game options menu:CascadeShadowFadeTreshold= - Decrease the value to improve the maximum view distance of shadowsCascadeShadowDistanceScale0= - Increase the value to improve the quality of close-range shadows (can significantly improve the fidelity of close range shadows with only a modest performance impact)CascadeShadowDistanceScale1= - Increase the value to improve the quality and visibility of close and medium-range shadows (will result in improved shadows, but not with such a striking effect as CascadeShadowDistanceScale0 and its performance impact is minimal)CascadeShadowDistanceScale2= - Increase the value to improve the quality and visibility of distant shadows significantly, at a minimal performance impactMaxTerrainShadowAtlasCount= - Increase the value to potentially improve the quality of terrain shadowsCascadeShadowmapSize= - Increase the value to slightly improve the fidelity of shadows and can make small objects cast more accurate shadows in certain in-game situations, at a moderate performance impactCascadeShadowQuality= - Increase the value to slightly improve the fidelity of shadows (best used in conjuction with CascadeShadowmapSize to enhance the detail and accuracy of shadows throughout the entire game at a minimal to moderate performance impact)The fidelity and accuracy of foliage shadows can also be increased by tweaking the following variable:FoliageShadowDistanceScale= - Increase the value to enable a few extra trees, bushes, and grass clumps to cast shadowsg) Texture Streaming TweaksAndrew Burnes revealed that the "Ultra" Texture Quality setting only increased the maximum number of textures stored in video memory, which can reduce texture pop-in. The amount of video memory dedicated to storing textures can be increased by tweaking the following variable:TextureMemoryBudget= The following texture-related variables can also be tweaked to increase the distance at which characters and general textures are streamed in, even though no immediate benefit was observed even with values doubled so far:TextureStreamingCharacterDistanceLimit= TextureStreamingHeadsDistanceLimit= TextureStreamingDistanceLimit= Source: Andrew Burnes (NVIDIA)
