엑스컴2 최적화 관련 자료를 찾다가 우연히 스팀포럼에 올라와 있는대로 설정하고나서 프레임 드랍이 확실히 많이 줄었습니다.

This WILL NOT fix choppy bink video playback as that is plugin based and not engine based. That is a different animal altogether (its very poorly coded for multi-core cpus)

THIS FIX WORKS FOR ALL UE3 BASED GAMES.(well tested)

I need to take a moment to explain that this will fix the kind of stutter that you get even on med to high-end hardware commonly called load/frame hitching. This is where your getting great Frames Per Sec (as reported by fraps or afterburner) but it "looks" choppy. Poor performace (I.E. running a game at settings you know your HW can't run well) will not see a serious decrease in hitching, though it will still help a fair bit. You can really tell the difference if you run with vsync ON and compare BEFORE FIX/AFTER FIX smoothness. It is very, very obvious. Anyhow....

ALL GAMES MUST HAVE COMPLETED FIRST RUN. (1 startup then exit)

1st Goto users yournamehere doc-uments my games gamename ...... config. 

(Note: EA games sometimes use "EA Games" instead of My Games)

Make a Backup of the "engine" ini file just in case you need it. 

2nd Open the "engine" ini file in notepad (or your text ed of choice) Find and change the following lines ( just use ctrl+F ) taking care to match the settings to your system where noted. Also some of these settings you may not have to change IF they already match what is given.

Here they are: (REMEMBER, READ CAREFULLY, MATCH EXACTLY)

"*"=setting

"bUseTextureStreaming=True" (these are default for most but not all UE3 games)

"bUseBackgroundLevelStreaming=True" 

"MipFadeInSpeed0=0" (these even out mipmap loads and draw time)

"MipFadeOutSpeed0=0"

"MipFadeInSpeed1=0"

"MipFadeOutSpeed1=0"

"PhysXGpuHeapSize=64" (these balance physx calls even on cpu based physx titles)

"PhysXMeshCacheSize=16"

"bSmoothFrameRate=TRUE" (this really does need to be on, ignore what you've read)

"MinSmoothedFrameRate=30" (keep these right here. setting higher/lower does no good)

"MaxSmoothedFrameRate=400"

"bInitializeShadersOnDemand=True" (reduces overall shader batch call size)

"DisableATITextureFilterOptimizationChecks=False" (driver based opt is MUCH faster)

"UseMinimalNVIDIADriverShaderOptimization=False" (same here)

"PoolSize=256" or (vidmem/poolsize exmpl: 512/128, 1024/256, etc, DO NOT exceed 768)

"bAllowMultiThreadedShaderCompile=True" (should already be on by default)

"ThreadedShaderCompileThreshold=4" (formulate like this: # of cpu-cores (not threads) -2)

"onlyStreamInTextures=True" (reduces overall texture batch call size)

Check for multiple instances of these settings within this file as some games have them listed twice and you must change both (I.E Xcom:Enemy Unkown)

Now save the file, then right click it, choose properties and then set it to "read-only". 

Launch your game, choose reset to defaults under that games graphics settings, then set them up how you want. These settings get saved to your profile file for that game and use the engine ini as a base. They are not saved to the ini file therefore it wont matter that it is read only. However there are a few rare exceptions (SEE NOTE BELOW)

THAT'S IT. 

All other settings in the file should be left at there defaults 

(Yes, even "SizeOfPermanentObjectPool". FYI This can hurt performance if set different from defaults because it can actually increase frame call time if set incorrectly)

All changes asume that you have steam cloud sync on. If not, changes you make may be overwritten if you turn on cloudsync after the fact and may need to be redone.

(SPECIAL NOTE) Some UE based game like BatmanAA or AC need to be configured how you want it 1st THEN do the fix minus the reset defaults part. You will also need to modify the "userengine" ini file in the same folder as the one above to match any relevent settings.

If you have done everything correctly YOU WILL NOTICE IT. Unlike other "fixes" the performance of this one will be VERY obvious, Especially for ATI/AMD owners. In fact the title screen loading for Dishonored is a dead giveaway (which is why I put this in here)

Special thanks to:

xbit411, lawn_dartmouth, z1g1t and the guys at the beta labs at AMD for help w/this

본문에도 있듯이 멀티코어 CPU사용하시는 분들 저를 포함해서 확실하게 효과가 있는거 같습니다.

수치를 무작정 변경하시기 전에 옆에 나와있는 작성자가 표기한 주의사항을 잘 읽어보시고 본인 시스템에 맞게 수치를 변경하세요

핵심은 C:UsersAdministrator(본인 계정명)/documents(내문서)/My games/XCOM2/XComGame/Config폴더로 가셔서 XComEngine.ini<---이 파일을 메모장이나 노트패드로 여신다음 위에 setting부분에 나와있는 설정값대로 바꿔주시면 됩니다(CTRL+F이용)

엑스컴2실행들어가시고나서 *그래픽설정에서 디폴트(보통)로 변경하시고 저장하신 다음 *반드시 전투1회*(완료 안하셔도 됨)를  실행(아무전투나 불러오기)하신후 바탕화면으로 나오기 하셔서 XComEngine.ini를 수정하신후에

수정한파일을 우클릭 속성 들어가셔서 읽기 전용으로 체크확인후 게임을 진행하셔야 합니다. 설정값만 고치고 바로 게임에 진행하시면 일부 수치가 변경이 안되네요  

모든 과정을 완료하시면 쾌적한 환경에서 플레이 하실 수 있을겁니다

"ThreadedShaderCompileThreshold=4" (formulate like this: # of cpu-cores (not threads) -2)<---이 부분에 대해서 궁금해 하시는거 같아 밑에 관련내용을 첨부합니다.

*본문내용을 잘 읽어 보시면 대부분 궁금한 점은 원작자가 다 설명해 놨습니다. 수정했는데 잘 안되셔서 답답한 마음에 댓들다시는건 알겠는데 제가 일일이 답변드리기 힘듭니다. 정말 궁금하시면  스팀 링크에 나와있는 원본제작자에게 질문하시는게 젤 빠를거 같습니다. 읽기전용이 왜 풀리는지, 본인 CPU쓰레드값 설정때문에 너무 스트레스 받지 마시라고 제가 다른 게시물에 단 댓글 일부분을 첨부하겠습니다.

원문내용을 분명히 잘 참조하시라고 했는데 제가 만든 트윅이 아니기 때문에 일일이 답변드리기 힘들어요ㅠ
